The <level> element

Parent elements: <attributes><backup><barline><direction><figure><figured-bass><forward><harmony><lyric><notations><note><part-group>

The level type is used to specify editorial information for different MusicXML elements. The content contains identifying and/or descriptive text about the editorial status of the parent element.

If the reference attribute is yes, this indicates editorial information that is for display only and should not affect playback. For instance, a modern edition of older music may set reference=“yes” on the attributes containing the music’s original clef, key, and time signature. It is no if not specified.

The type attribute indicates whether the editorial information applies to the start of a series of symbols, the end of a series of symbols, or a single symbol. It is single if not specified for compatibility with earlier MusicXML versions.
