contexttools.TimeSignatureMark

class abjad.tools.contexttools.TimeSignatureMark.TimeSignatureMark.TimeSignatureMark(*args, **kwargs)

New in version 2.0.

Abjad model of a time signature:

abjad> staff = Staff("c'8 d'8 e'8 f'8")

abjad> contexttools.TimeSignatureMark((4, 8))(staff[0])
TimeSignatureMark((4, 8))(c'8)

abjad> f(staff)
\new Staff {
    \time 4/8
    c'8
    d'8
    e'8
    f'8
}

Abjad time signature marks target staff context by default.

Initialize time signature marks to score context like this:

abjad> contexttools.TimeSignatureMark((4, 8), target_context = Score)
TimeSignatureMark((4, 8), target_context = Score)

Time signatures are immutable.

abjad> context_mark.target_context is None
True

Return context mark or none.
