Multiple lyrics syllables assigned to a single note are implemented either using a space in the <text> child of <lyric>, or by using <elision>. The first note has a single syllable, the second note has two syllables separated by a space, the third has two syllables with <elision> set to an undertie, and the fourth has three syllables (the first and third one in red, and the second one being in italic and overriding the color with blue), with a green undertie between the first and second syllable and an empty <elision> element between the second and third syllable, causing an application-specific elision glyph. None of the <lyric> elements has the ‘number’ attribute set. MusicXML Part 1 0 major 4 4 G 2 C 5 4 1 whole a C 5 4 1 whole b c C 5 4 1 whole d ‿ e C 5 4 1 whole f ‿ g h light-heavy
