pub fn verticality_at(
stream: &Stream,
offset: FloatType,
) -> Vec<(usize, Vec<StreamElement>)>Expand description
What is sounding or standing in each part at an offset, part by part:
music21’s getVerticalityFromObject, asked by offset since a stream here
owns its notes and an offset is what says where one is.
A thing counts if it starts there or is still going, and a thing of no length counts where it stands. Parts holding nothing there are left out, so each answer carries the index of its part.
