Module notation 

Ties, noteheads, stem direction, colour, lyrics and beams. Notation attached to a note or a chord: ties, noteheads, stem direction, colour and lyrics.

These are the parts of music21’s note.NotRest and note.GeneralNote that carry musical intent rather than layout. A tie says two written notes sound as one; a diamond notehead says a string harmonic; a lyric is the text sung on the note. None of them need a stream to mean something, which is why they live in the data model here alongside pitch and duration.
