Inheritance diagram of abjad.tools.spannertools.TrillSpanner.TrillSpanner.TrillSpanner

class abjad.tools.spannertools.TrillSpanner.TrillSpanner.TrillSpanner(components=None)[source]

Abjad trill spanner:

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

abjad> spannertools.TrillSpanner(staff[:])
TrillSpanner(c'8, d'8, e'8, f'8)
abjad> f(staff)
\new Staff {
    c'8 \startTrillSpan
    d'8
    e'8
    f'8 \stopTrillSpan
}

Override LilyPond TrillSpanner grob.

Return trill spanner.

Read-only Properties

TrillSpanner.components

Return read-only tuple of components in spanner.

abjad> voice = Voice("c'8 d'8 e'8 f'8")
abjad> spanner = spannertools.Spanner(voice[:2])
abjad> spanner.components
(Note("c'8"), Note("d'8"))

Changed in version 1.1: Now returns an (immutable) tuple instead of a (mutable) list.

Note

Inherited from spannertools.Spanner

TrillSpanner.duration_in_seconds

Sum of duration of all leaves in spanner, in seconds.

Note

Inherited from spannertools.Spanner

TrillSpanner.leaves

Return read-only tuple of leaves in spanner.

abjad> voice = Voice("c'8 d'8 e'8 f'8")
abjad> spanner = spannertools.Spanner(voice[:2])
abjad> spanner.leaves
(Note("c'8"), Note("d'8"))

Changed in version 1.1: Now returns an (immutable) tuple instead of a (mutable) list.

Note

When dealing with large, complex scores accessing this attribute can take some time. Best to make a local copy with leaves = spanner.leaves first. Or use spanner- specific iteration tools.

Note

Inherited from spannertools.Spanner

TrillSpanner.offset

New in version 1.1.

Return read-only reference to spanner offset interface.

Spanner offset interface implements start and stop attributes.
