5.1. Introduction¶

Abjad publishes information about many durated score objects.

Notes, rests, chords and skips carry some duration attributes:

abjad> note = Note(0, (3, 16))
abjad> measure = Measure((3, 16), [note])
abjad> staff = stafftools.RhythmicStaff([measure])
abjad> note.written_duration
Duration(3, 16)

Tuplets, measures, voices, staves and the other containers carry duration attributes, too:

abjad> tuplet = tuplettools.FixedDurationTuplet(Duration(3, 16), Note(0, (1, 16)) * 5)
abjad> measure = Measure((3, 16), [tuplet])
abjad> staff = stafftools.RhythmicStaff([measure])
abjad> tuplet.multiplier
Duration(3, 5)

The next chapters document core duration concepts in Abjad.
