<xs:documentation>MusicXML W3C XML schema (XSD)
Version 4.0
Copyright © 2004-2021 the Contributors to the MusicXML Specification, published by the W3C Music Notation Community Group under the W3C Community Final Specification Agreement (FSA):

A human-readable summary is available:

This is the W3C XML Schema (XSD) version of the MusicXML 4.0 format. Validation is tightened by moving MusicXML definitions from comments into schema data types and definitions. Character entities and other entity usages that are not supported in W3C XML Schema have been removed. The features of W3C XML Schema make it easier to define variations of the MusicXML format, either via extension or restriction.
This file defines the MusicXML 4.0 XSD, including the score-partwise and score-timewise document elements.
The XML catalog at catalog.xml supports validating against a local copy of this XSD rather than the networked version. Software often has trouble using system IDs due to factors such as restrictions on network access, or resources having moved from the original specified location. To validate with the MusicXML XSD, use a schema URI of "http://www.musicxml.org/xsd/musicxml.xsd".</xs:documentation>
</xs:annotation>
<xs:annotation>
<xs:documentation>The MusicXML 4.0 DTD has no namespace, so for compatibility the MusicXML 4.0 XSD has no namespace either. Those who need to import the MusicXML XSD into another schema are advised to create a new version that uses "http://www.musicxml.org/xsd/MusicXML" as the namespace.</xs:documentation>

<xs:annotation>
<xs:documentation>The color type indicates the color of an element. Color may be represented as hexadecimal RGB triples, as in HTML, or as hexadecimal ARGB tuples, with the A indicating alpha of transparency. An alpha value of 00 is totally transparent; FF is totally opaque. If RGB is used, the A value is assumed to be FF.
For instance, the RGB value "#800080" represents purple. An ARGB value of "#40800080" would be a transparent purple.
As in SVG 1.1, colors are defined in terms of the sRGB color space (IEC 61966).</xs:documentation>

<xs:simpleType name="number-level">
<xs:annotation>
<xs:documentation>Slurs, tuplets, and many other features can be concurrent and overlap within a single musical part. The number-level entity distinguishes up to 16 concurrent objects of the same type when the objects overlap in MusicXML document order. Values greater than 6 are usually only needed for music with a large number of divisi staves in a single part, or if there are more than 6 cross-staff arpeggios in a single measure. When a number-level value is implied, the value is 1 by default.
When polyphonic parts are involved, the ordering within a MusicXML document can differ from musical score order. As an example, say we have a piano part in 4/4 where within a single measure, all the notes on the top staff are followed by all the notes on the bottom staff. In this example, each staff has a slur that starts on beat 2 and stops on beat 3, and there is a third slur that goes from beat 1 of one staff to beat 4 of the other staff.
In this situation, the two mid-measure slurs can use the same number because they do not overlap in MusicXML document order, even though they do overlap in musical score order. Within the MusicXML document, the top staff slur will both start and stop before the bottom staff slur starts and stops.
If the cross-staff slur starts in the top staff and stops in the bottom staff, it will need a separate number from the mid-measure slurs because it overlaps those slurs in MusicXML document order. However, if the cross-staff slur starts in the bottom staff and stops in the top staff, all three slurs can use the same number. None of them overlap within the MusicXML document, even though they all overlap each other in the musical score order. Within the MusicXML document, the start and stop of the top-staff slur will be followed by the stop and start of the cross-staff slur, followed by the start and stop of the bottom-staff slur.
As this example demonstrates, a reading program should be prepared to handle cases where the number-levels start and stop in an arbitrary order. Because the start and stop values refer to musical score order, a program may find the stopping point of an object earlier in the MusicXML document than it will find its starting point.</xs:documentation>

Distances in a MusicXML file are measured in tenths of staff space. Tenths are then scaled to millimeters within the scaling element, used in the defaults element at the start of a score. Individual staves can apply a scaling factor to adjust staff size.

A tied element which joins two notes of the same pitch can be specified with tied-type start on the first note and tied-type stop on the second note. To indicate a note should be undamped, use a single tied element with tied-type let-ring. For other ties that are visually attached to a single note, such as a tie leading into or out of a repeated section or coda, use two tied elements on the same note, one start and one stop.
In start-stop cases, ties can add more elements using a continue type. This is typically used to specify the formatting of cross-system ties.
When multiple elements with the same tag are used within the same note, their order within the MusicXML document should match the musical score order. For example, a note with a tie at the end of a first ending should have the tied element with a type of start precede the tied element with a type of stop.</xs:documentation>

A cue staff represents music from another part. An alternate staff shares the same music as the prior staff, but displayed differently (e.g., treble and bass clef, standard notation and tablature).

<xs:documentation>The pedal-type simple type is used to distinguish types of pedal directions. The start value indicates the start of a damper pedal, while the sostenuto value indicates the start of a sostenuto pedal. The other values can be used with either the damper or sostenuto pedal. The soft pedal is not included here because there is no special symbol or graphic used for it beyond what can be specified with words and bracket elements.
The change, continue, discontinue, and resume types are used when the line attribute is yes. The change type indicates a pedal lift and retake indicated with an inverted V marking. The continue type allows more precise formatting across system breaks and for more complex pedaling lines. The discontinue type indicates the end of a pedal line that does not include the explicit lift represented by the stop type. The resume type indicates the start of a pedal line that does not include the downstroke represented by the start type. It can be used when a line resumes after being discontinued, or to start a pedal line that is preceded by a text or symbol representation of the pedal.</xs:documentation>

<xs:documentation>
The notehead-value type indicates shapes other than the open and closed ovals associated with note durations.
The values do, re, mi, fa, fa up, so, la, and ti correspond to Aikin's 7-shape system. The fa up shape is typically used with upstems; the fa shape is typically used with downstems or no stems.
The arrow shapes differ from triangle and inverted triangle by being centered on the stem. Slashed and back slashed notes include both the normal notehead and a slash. The triangle shape has the tip of the triangle pointing up; the inverted triangle shape has the tip of the triangle pointing down. The left triangle shape is a right triangle with the hypotenuse facing up and to the left.
The other notehead covers noteheads other than those listed here. It is usually used in combination with the smufl attribute to specify a particular SMuFL notehead. The smufl attribute may be used with any notehead value to help specify the appearance of symbols that share the same MusicXML semantics. Noteheads in the SMuFL Note name noteheads and Note name noteheads supplement ranges (U+E150–U+E1AF and U+EEE0–U+EEFF) should not use the smufl attribute or the "other" value, but instead use the notehead-text element.</xs:documentation>

Normal slurs, S-shaped slurs, and ties need only two bezier points: one associated with the start of the slur or tie, the other with the stop. Complex slurs and slurs divided over system breaks can specify additional bezier data at slur elements with a continue type.
The bezier-x, bezier-y, and bezier-offset attributes describe the outgoing bezier point for slurs and ties with a start type, and the incoming bezier point for slurs and ties with types of stop or continue. The bezier-x2, bezier-y2, and bezier-offset2 attributes are only valid with slurs of type continue, and describe the outgoing bezier point.
The bezier-x, bezier-y, bezier-x2, and bezier-y2 attributes are specified in tenths, relative to any position settings associated with the slur or tied element. The bezier-offset and bezier-offset2 attributes are measured in terms of musical divisions, like the offset element.
The bezier-offset and bezier-offset2 attributes are deprecated as of MusicXML 3.1. If both the bezier-x and bezier-offset attributes are present, the bezier-x attribute takes priority.

<xs:attributeGroup name="position">
<xs:annotation>
<xs:documentation>For most elements, any program will compute a default x and y position. The position attributes let this be changed two ways.
The default-x and default-y attributes change the computation of the default position. For most elements, the origin is changed relative to the left-hand side of the note or the musical position within the bar (x) and the top line of the staff (y).
For the following elements, the default-x value changes the origin relative to the start of the current measure:
- note
- figured-bass
- harmony
- link
- directive
- measure-numbering
- all descendants of the part-list element
- all children of the direction-type element
This origin is from the start of the entire measure, at either the left barline or the start of the system.
When the default-x attribute is used within a child element of the part-name-display, part-abbreviation-display, group-name-display, or group-abbreviation-display elements, it changes the origin relative to the start of the first measure on the system. These values are used when the current measure or a succeeding measure starts a new system. The same change of origin is used for the group-symbol element.
For the note, figured-bass, and harmony elements, the default-x value is considered to have adjusted the musical position within the bar for its descendant elements.
Since the credit-words and credit-image elements are not related to a measure, in these cases the default-x and default-y attributes adjust the origin relative to the bottom left-hand corner of the specified page.
The relative-x and relative-y attributes change the position relative to the default position, either as computed by the individual program, or as overridden by the default-x and default-y attributes.
Positive x is right, negative x is left; positive y is up, negative y is down. All units are in tenths of interline space. For stems, positive relative-y lengthens a stem while negative relative-y shortens it.
The default-x and default-y position attributes provide higher-resolution positioning data than related features such as the placement attribute and the offset element. Applications reading a MusicXML file that can understand both features should generally rely on the default-x and default-y attributes for their greater accuracy. For the relative-x and relative-y attributes, the offset element, placement attribute, and directive attribute provide context for the relative position information, so the two features should be interpreted together.
As elsewhere in the MusicXML format, tenths are the global tenths defined by the scaling element, not the local tenths of a staff resized by the staff-size element.</xs:documentation>

<xs:documentation>The element and position attributes are new as of Version 2.0. They allow for bookmarks and links to be positioned at higher resolution than the level of music-data elements. When no element and position attributes are present, the bookmark or link element refers to the next sibling element in the MusicXML file. The element attribute specifies an element type for a descendant of the next sibling element that is not a link or bookmark. The position attribute specifies the position of this descendant element, where the first position is 1. The position attribute is ignored if the element attribute is not present. For instance, an element value of "beam" and a position value of "2" defines the link or bookmark to refer to the second beam descendant of the next sibling element that is not a link or bookmark. This is equivalent to an XPath test of [.//beam[2]] done in the context of the sibling element.</xs:documentation>

<xs:attributeGroup name="measure-attributes">
<xs:annotation>
<xs:documentation>The measure-attributes group is used by the measure element. Measures have a required number attribute (going from partwise to timewise, measures are grouped via the number).
The implicit attribute is set to "yes" for measures where the measure number should never appear, such as pickup measures and the last half of mid-measure repeats. The value is "no" if not specified.
The non-controlling attribute is intended for use in multimetric music like the Don Giovanni minuet. If set to "yes", the left barline in this measure does not coincide with the left barline of measures in other parts. The value is "no" if not specified.
In partwise files, the number attribute should be the same for measures in different parts that share the same left barline. While the number attribute is often numeric, it does not have to be. Non-numeric values are typically used together with the implicit or non-controlling attributes being set to "yes". For a pickup measure, the number attribute is typically set to "0" and the implicit attribute is typically set to "yes".
If measure numbers are not unique within a part, this can cause problems for conversions between partwise and timewise formats. The text attribute allows specification of displayed measure numbers that are different than what is used in the number attribute. This attribute is ignored for measures where the implicit attribute is set to "yes". Further details about measure numbering can be specified using the measure-numbering element.
Measure width is specified in tenths. These are the global tenths specified in the scaling element, not local tenths as modified by the staff-size element. The width covers the entire measure from barline or system start to barline or system end.</xs:documentation>

<xs:annotation>
<xs:documentation>Dynamics can be associated either with a note or a general musical direction. To avoid inconsistencies between and amongst the letter abbreviations for dynamics (what is sf vs. sfz, standing alone or with a trailing dynamic that is not always piano), we use the actual letters as the names of these dynamic elements. The other-dynamics element allows other dynamic marks that are not covered here. Dynamics elements may also be combined to create marks not covered by a single element, such as sfmp.
These letter dynamic symbols are separated from crescendo, decrescendo, and wedge indications. Dynamic representation is inconsistent in scores. Many things are assumed by the composer and left out, such as returns to original dynamics. The MusicXML format captures what is in the score, but does not try to be optimal for analysis or synthesis of dynamics.
The placement attribute is used when the dynamics are associated with a note. It is ignored when the dynamics are associated with a direction. In that case the direction element's placement attribute is used instead.</xs:documentation>

<xs:documentation>The staff-size element indicates how large a staff space is on this staff, expressed as a percentage of the work's default scaling.

A staff-type of cue, ossia, or editorial implies a staff-size of less than 100, but the exact value is implementation-dependent unless specified here. Staff size affects staff height only, not the relationship of the staff to the left and right margins.
In some cases, a staff-size different than 100 also scales the notation on the staff, such as with a cue staff. In other cases, such as percussion staves, the lines may be more widely spaced without scaling the notation on the staff. The scaling attribute allows these two cases to be distinguished. It specifies the percentage scaling that applies to the notation. Values less that 100 make the notation smaller while values over 100 make the notation larger.

<xs:annotation>
<xs:documentation>If a barline is other than a normal single barline, it should be represented by a barline type that describes it. This includes information about repeats and multiple endings, as well as line style. Barline data is on the same level as the other musical data in a score - a child of a measure in a partwise score, or a part in a timewise score. This allows for barlines within measures, as in dotted barlines that subdivide measures in complex meters. The two fermata elements allow for fermatas on both sides of the barline (the lower one inverted).
Barlines have a location attribute to make it easier to process barlines independently of the other musical data in a score. It is often easier to set up measures separately from entering notes. The location attribute must match where the barline element occurs within the rest of the musical data in the score. If location is left, it should be the first element in the measure, aside from the print, bookmark, and link elements. If location is right, it should be the last element, again with the possible exception of the print, bookmark, and link elements. If no location is specified, the right barline is the default. The segno, coda, and divisions attributes work the same way as in the sound element. They are used for playback when barline elements contain segno or coda child elements.</xs:documentation>

<xs:documentation>The ending type represents multiple (e.g. first and second) endings. Typically, the start type is associated with the left barline of the first measure in an ending. The stop and discontinue types are associated with the right barline of the last measure in an ending. Stop is used when the ending mark concludes with a downward jog, as is typical for first endings. Discontinue is used when there is no downward jog, as is typical for second endings that do not conclude a piece. The length of the jog can be specified using the end-length attribute. The text-x and text-y attributes are offsets that specify where the baseline of the start of the ending text appears, relative to the start of the ending line.
The number attribute indicates which times the ending is played, similar to the time-only attribute used by other elements. While this often represents the numeric values for what is under the ending line, it can also indicate whether an ending is played during a larger dal segno or da capo repeat. Single endings such as "1" or comma-separated multiple endings such as "1,2" may be used. The ending element text is used when the text displayed in the ending is different than what appears in the number attribute. The print-object attribute is used to indicate when an ending is present but not printed, as is often the case for many parts in a full score.</xs:documentation>

<xs:documentation>Kind indicates the type of chord. Degree elements can then add, subtract, or alter from these starting points
The attributes are used to indicate the formatting of the symbol. Since the kind element is the constant in all the harmony-chord groups that can make up a polychord, many formatting attributes are here.
The use-symbols attribute is yes if the kind should be represented when possible with harmony symbols rather than letters and numbers. These symbols include:
major: a triangle, like Unicode 25B3
minor: -, like Unicode 002D
augmented: +, like Unicode 002B
diminished: °, like Unicode 00B0
half-diminished: ø, like Unicode 00F8
For the major-minor kind, only the minor symbol is used when use-symbols is yes. The major symbol is set using the symbol attribute in the degree-value element. The corresponding degree-alter value will usually be 0 in this case.
The text attribute describes how the kind should be spelled in a score. If use-symbols is yes, the value of the text attribute follows the symbol. The stack-degrees attribute is yes if the degree elements should be stacked above each other. The parentheses-degrees attribute is yes if all the degrees should be in parentheses. The bracket-degrees attribute is yes if all the degrees should be in a bracket. If not specified, these values are implementation-specific. The alignment attributes are for the entire harmony-chord group of which this kind element is a part.
The text attribute may use strings such as "13sus" that refer to both the kind and one or more degree elements. In this case, the corresponding degree elements should have the print-object attribute set to "no" to keep redundant alterations from being displayed.</xs:documentation>

<xs:complexType name="sound">
<xs:annotation>
<xs:documentation>The sound element contains general playback parameters. They can stand alone within a part/measure, or be a component element within a direction.
Tempo is expressed in quarter notes per minute. If 0, the sound-generating program should prompt the user at the time of compiling a sound (MIDI) file.
Dynamics (or MIDI velocity) are expressed as a percentage of the default forte value (90 for MIDI 1.0).
Dacapo indicates to go back to the beginning of the movement. When used it always has the value "yes".
Segno and dalsegno are used for backwards jumps to a segno sign; coda and tocoda are used for forward jumps to a coda sign. If there are multiple jumps, the value of these parameters can be used to name and distinguish them. If segno or coda is used, the divisions attribute can also be used to indicate the number of divisions per quarter note. Otherwise sound and MIDI generating programs may have to recompute this.
By default, a dalsegno or dacapo attribute indicates that the jump should occur the first time through, while a tocoda attribute indicates the jump should occur the second time through. The time that jumps occur can be changed by using the time-only attribute.
The forward-repeat attribute indicates that a forward repeat sign is implied but not displayed. It is used for example in two-part forms with repeats, such as a minuet and trio where no repeat is displayed at the start of the trio. This usually occurs after a barline. When used it always has the value of "yes".
The fine attribute follows the final note or rest in a movement with a da capo or dal segno direction. If numeric, the value represents the actual duration of the final note or rest, which can be ambiguous in written notation and different among parts and voices. The value may also be "yes" to indicate no change to the final duration.
If the sound element applies only particular times through a repeat, the time-only attribute indicates which times to apply the sound element.
Pizzicato in a sound element effects all following notes. Yes indicates pizzicato, no indicates arco.
The pan and elevation attributes are deprecated in Version 2.0. The pan and elevation elements in the midi-instrument element should be used instead. The meaning of the pan and elevation attributes is the same as for the pan and elevation elements. If both are present, the mid-instrument elements take priority.
The damper-pedal, soft-pedal, and sostenuto-pedal attributes effect playback of the three common piano pedals and their MIDI controller equivalents. The yes value indicates the pedal is depressed; no indicates the pedal is released. A numeric value from 0 to 100 may also be used for half pedaling. This value is the percentage that the pedal is depressed. A value of 0 is equivalent to no, and a value of 100 is equivalent to yes.
Instrument changes, MIDI devices, MIDI instruments, and playback techniques are changed using the instrument-change, midi-device, midi-instrument, and play elements. When there are multiple instances of these elements, they should be grouped together by instrument using the id attribute values.
The offset element is used to indicate that the sound takes place offset from the current score position. If the sound element is a child of a direction element, the sound offset element overrides the direction offset element if both elements are present. Note that the offset reflects the intended musical position for the change in sound. It should not be used to compensate for latency issues in particular hardware configurations.</xs:documentation>

The first and second elements are positive integers that specify the ratio between durations of consecutive notes. For example, a first element with a value of 2 and a second element with a value of 1 applied to eighth notes specifies a quarter note / eighth note tuplet playback, where the first note is twice as long as the second note. Ratios should be specified with the smallest integers possible. For example, a ratio of 6 to 4 should be specified as 3 to 2 instead.
The optional swing-type element specifies the note type, either eighth or 16th, to which the ratio is applied. The value is eighth if this element is not present.
The optional swing-style element is a string describing the style of swing used.
The swing element has no effect for playback of grace notes, notes where a type element is not present, and notes where the specified duration is different than the nominal value associated with the specified type.

<xs:documentation>A system is a group of staves that are read and played simultaneously. System layout includes left and right margins and the vertical distance from the previous system. The system distance is measured from the bottom line of the previous system to the top line of the current system. It is ignored for the first system on a page. The top system distance is measured from the page's top margin to the top line of the first system. It is ignored for all but the first system on a page.
Sometimes the sum of measure widths in a system may not equal the system width specified by the layout elements due to roundoff or other errors. The behavior when reading MusicXML files in these cases is application-dependent. For instance, applications may find that the system layout data is more reliable than the sum of the measure widths, and adjust the measure widths accordingly.
When used in the defaults element, the system-layout element defines a default appearance for all systems in the score. If no system-layout element is present in the defaults element, default system layout values are chosen by the application.
When used in the print element, the system-layout element affects the appearance of the current system only. All other systems use the default values as determined by the defaults element. If any child elements are missing from the system-layout element in a print element, the values determined by the defaults element are used there as well.

The lyric number indicates multiple lines, though a name can be used as well. Common name examples are verse and chorus.
Justification is center by default; placement is below by default. Vertical alignment is to the baseline of the text and horizontal alignment matches justification. The print-object attribute can override a note's print-lyric attribute in cases where only some lyrics on a note are printed, as when lyrics for later verses are printed in a block of text rather than with each note. The time-only attribute precisely specifies which lyrics are to be sung which time through a repeated section.</xs:documentation>

<xs:annotation>
<xs:documentation>Notes are the most common type of MusicXML data. The MusicXML format distinguishes between elements used for sound information and elements used for notation information (e.g., tie is used for sound, tied for notation). Thus grace notes do not have a duration element. Cue notes have a duration element, as do forward elements, but no tie elements. Having these two types of information available can make interchange easier, as some programs handle one type of information more readily than the other.
The print-leger attribute is used to indicate whether leger lines are printed. Notes without leger lines are used to indicate indeterminate high and low notes. By default, it is set to yes. If print-object is set to no, print-leger is interpreted to also be set to no if not present. This attribute is ignored for rests.
The dynamics and end-dynamics attributes correspond to MIDI 1.0's Note On and Note Off velocities, respectively. They are expressed in terms of percentages of the default forte value (90 for MIDI 1.0).
The attack and release attributes are used to alter the starting and stopping time of the note from when it would otherwise occur based on the flow of durations - information that is specific to a performance. They are expressed in terms of divisions, either positive or negative. A note that starts a tie should not have a release attribute, and a note that stops a tie should not have an attack attribute. The attack and release attributes are independent of each other. The attack attribute only changes the starting time of a note, and the release attribute only changes the stopping time of a note.
If a note is played only particular times through a repeat, the time-only attribute shows which times to play the note.
The pizzicato attribute is used when just this note is sounded pizzicato, vs. the pizzicato element which changes overall playback between pizzicato and arco.</xs:documentation>

Using the other-notation type without the smufl attribute allows for extended representation, though without application interoperability.</xs:documentation>

The number attribute is rarely needed to disambiguate ties, since note pitches will usually suffice. The attribute is implied rather than defaulting to 1 as with most elements. It is available for use in more complex tied notation situations.
Ties that join two notes of the same pitch together should be represented with a tied element on the first note with type="start" and a tied element on the second note with type="stop". This can also be done if the two notes being tied are enharmonically equivalent, but have different step values. It is not recommended to use tied elements to join two notes with enharmonically inequivalent pitches.
Ties that indicate that an instrument should be undamped are specified with a single tied element with type="let-ring".
Ties that are visually attached to only one note, other than undamped ties, should be specified with two tied elements on the same note, first type="start" then type="stop". This can be used to represent ties into or out of repeated sections or codas.</xs:documentation>

Single-note tremolos use the single type, double-note tremolos use the start and stop types, and unmeasured tremolos use the unmeasured type. The default is "single" for compatibility with Version 1.1. The text of the element indicates the number of tremolo marks and is an integer from 0 to 8. Note that the number of attached beams is not included in this value, but is represented separately using the beam element. The value should be 0 for unmeasured tremolos.
When using double-note tremolos, the duration of each note in the tremolo should correspond to half of the notated type value. A time-modification element should also be added with an actual-notes value of 2 and a normal-notes value of 1. If used within a tuplet, this 2/1 ratio should be multiplied by the existing tuplet ratio.
The smufl attribute specifies the glyph to use from the SMuFL Tremolos range for an unmeasured tremolo. It is ignored for other tremolo types. The SMuFL buzzRoll glyph is used by default if the attribute is missing.
Using repeater beams for indicating tremolos is deprecated as of MusicXML 3.0.</xs:documentation>

Whereas a time-modification element shows how the cumulative, sounding effect of tuplets and double-note tremolos compare to the written note type, the tuplet element describes how this is displayed. The tuplet element also provides more detailed representation information than the time-modification element, and is needed to represent nested tuplets and other complex tuplets accurately.
The show-number attribute is used to display either the number of actual notes, the number of both actual and normal notes, or neither. It is actual by default.

The credit-words, credit-symbol, and credit-image elements are similar to the words, symbol, and image elements for directions. However, since the credit is not part of a measure, the default-x and default-y attributes adjust the origin relative to the bottom left-hand corner of the page. The enclosure for credit-words and credit-symbol is none by default.
By default, a series of credit-words and credit-symbol elements within a single credit element follow one another in sequence visually. Non-positional formatting attributes are carried over from the previous element by default.
The page attribute for the credit element specifies the page number where the credit should appear. This is an integer value that starts with 1 for the first page. Its value is 1 by default. Since credits occur before the music, these page numbers do not refer to the page numbering specified by the print element's page-number attribute.
The credit-type element indicates the purpose behind a credit. Multiple types of data may be combined in a single credit, so multiple elements may be used. Standard values include page number, title, subtitle, composer, arranger, lyricist, rights, and part name.

A part-group element is not needed for a single multi-staff part. By default, multi-staff parts include a brace symbol and (if appropriate given the bar-style) common barlines. The symbol formatting for a multi-staff part can be more fully specified using the part-symbol element.</xs:documentation>

<xs:element name="duration" type="positive-divisions">
<xs:annotation>
<xs:documentation>Duration is a positive number specified in division units. This is the intended duration vs. notated duration (for instance, differences in dotted notes in Baroque-era music). Differences in duration specific to an interpretation or performance should be represented using the note element's attack and release attributes.
The duration element moves the musical position when used in backup elements, forward elements, and note elements that do not contain a chord child element.</xs:documentation>

<xs:documentation>The display-step-octave group contains the sequence of elements used by both the rest and unpitched elements. This group is used to place rests and unpitched elements on the staff without implying that these elements have pitch. Positioning follows the current clef. If percussion clef is used, the display-step and display-octave elements are interpreted as if in treble clef, with a G in octave 4 on line 2.</xs:documentation>

<xs:annotation>
<xs:documentation>The full-note group is a sequence of the common note elements between cue/grace notes and regular (full) notes: pitch, chord, and rest information, but not duration (cue and grace notes do not have duration encoded). Unpitched elements are used for unpitched percussion, speaking voice, and other musical elements lacking determinate pitch.</xs:documentation>

<xs:element name="chord" type="empty" minOccurs="0">
<xs:annotation>
<xs:documentation>The chord element indicates that this note is an additional chord tone with the preceding note.
The duration of a chord note does not move the musical position within a measure. That is done by the duration of the first preceding note without a chord element. Thus the duration of a chord note cannot be longer than the preceding note.
In most cases the duration will be the same as the preceding note. However it can be shorter in situations such as multiple stops for string instruments.</xs:documentation>
