pub fn tie_pitch_set(element: &StreamElement) -> Option<Vec<String>>Expand description
The notes a note or chord ties forward, by name: music21’s
getTiePitchSet.
Nothing at all where the element is no note – a rest or a barline
ties nothing, and music21 answers None for either – and an empty
list where it ties nothing on. A stroke with no pitch is left out, as
music21 leaves it out, so a percussion chord of strokes alone ties
nothing.
