Content
Always empty.
Attributes
| Name | Type | Required? | Description |
|---|---|---|---|
| type | start-stop-continue | Yes | Indicates if this is the start, stop, or continuation of the wavy line. The value should be continue whenever used within a <barline> element. |
| accelerate | yes-no | No | If yes, the trill accelerates during playback. It is no if not specified. |
| beats | trill-beats | No | The number of distinct notes during playback, counting the starting note but not the two-note turn. It is 4 if not specified. |
| color | color | No | Indicates the color of an element. |
| default-x | tenths | No | Changes the computation of the default horizontal position. The origin is changed relative to the left-hand side of the note or the musical position within the bar. Positive x is right and negative x is left. This attribute provides higher-resolution positioning data than the <offset> element. Applications reading a MusicXML file that can understand both features should generally rely on this attribute for its greater accuracy. |
| default-y | tenths | No | Changes the computation of the default vertical position. The origin is changed relative to the top line of the staff. Positive y is up and negative y is down. This attribute provides higher-resolution positioning data than the placement attribute. Applications reading a MusicXML file that can understand both attributes should generally rely on this attribute for its greater accuracy. |
| last-beat | percent | No | The percentage of the way through the duration for landing on the last beat. It is 75 if not specified. |
| number | number-level | No | Distinguishes multiple wavy lines when they overlap in MusicXML document order. |
| placement | above-below | No | Indicates whether something is above or below another element, such as a note or a notation. |
| relative-x | tenths | No | Changes the horizontal position relative to the default position, either as computed by the individual program, or as overridden by the default-x attribute. Positive x is right and negative x is left. It should be interpreted in the context of the <offset> element or directive attribute if those are present. |
| relative-y | tenths | No | Changes the vertical position relative to the default position, either as computed by the individual program, or as overridden by the default-y attribute. Positive y is up and negative y is down. It should be interpreted in the context of the placement attribute if that is present. |
| second-beat | percent | No | The percentage of the way through the duration for landing on the second beat. It is 25 if not specified. |
| smufl | smufl-wavy-line-glyph-name | No | Specifies a particular wavy line glyph from the Standard Music Font Layout (SMuFL) Multi-segment lines range. |
| start-note | start-note | No | The starting note for playback, relative to the current note. It is upper if not specified. |
| trill-step | trill-step | No | The alternating note for playback, relative to the current note. It is whole if not specified. |
| two-note-turn | two-note-turn | No | Specifies the two-note turn included at the end of the trill, if any. It is none if not specified. |
