New in version 2.0.
Label pitch-classes of every vertical moment in expr:
abjad> from abjad.tools import verticalitytools
abjad> score = Score(Staff([]) * 3)
abjad> notes = [Note("c'8"), Note("d'8"), Note("e'8"), Note("f'8")]
abjad> score[0].extend(notes)
abjad> contexttools.ClefMark('alto')(score[1])
ClefMark('alto')(Staff{})
abjad> score[1].extend([Note(-5, (1, 4)), Note(-7, (1, 4))])
abjad> contexttools.ClefMark('bass')(score[2])
ClefMark('bass')(Staff{})
abjad> score[2].append(Note(-24, (1, 2)))
abjad> verticalitytools.label_vertical_moments_in_expr_with_numbered_chromatic_pitch_classes(score)
abjad> f(score)
\new Score <<
\new Staff {
c'8
d'8 _ \markup { \small { \column { 7 2 0 } } }
e'8
f'8 _ \markup { \small { \column { 5 0 } } }
}
\new Staff {
\clef "alto"
g4
f4 _ \markup { \small { \column { 5 4 0 } } }
}
\new Staff {
\clef "bass"
c,2 _ \markup { \small { \column { 7 0 } } }
}

Changed in version 2.0: renamed label.vertical_moment_pitch_classes() to verticalitytools.label_vertical_moments_in_expr_with_numbered_chromatic_pitch_classes().
