beam-level data type
The MusicXML format supports six levels of beaming, up to 1024th notes. Unlike the number-level type, the beam-level type identifies concurrent beams in a beam group. It does not distinguish overlapping beams such as grace notes within regular notes, or beams used in different voices.
