Module segment 

A part cut into segments of braille music, measure by measure and grouping by grouping: music21’s braille.segment and braille.noteGrouping.

music21 marks the notes of the part it transcribes with attributes for the time it transcribes them – the slurs over them, how their beams read, a full measure’s rest – and writes each sign’s English onto the element. Here each element of a segment is a BrailleElement that carries those beside a copy of the element.

Structs

BrailleElement

An element of a segment with what music21 keeps on it while transcribing: where it stands, its affinity, how it sorts, its English, its note context, and a key signature’s predecessor.

BrailleElementGrouping

A grouping of elements written together: music21’s BrailleElementGrouping.

BrailleGrandSegment

A piano’s two staves cut into segments of groupings for each hand, written side by side: music21’s BrailleGrandSegment.

BrailleSegment

A part cut into segments of groupings, ready to transcribe: music21’s BrailleSegment.

NoteGroupingTranscriber

Writes the elements of a grouping one after another, octaves where needed: music21’s NoteGroupingTranscriber.

SegmentKey

Where a grouping stands: its measure, its place among the measure’s groupings, its kind and its hand: music21’s SegmentKey.

SegmentOptions

The options music21’s translation takes, as a segment reads them.

SegmentTranscriber

A segment written into a text a step at a time, with what music21’s segment keeps while it writes: the keys still to write, the grouping being written and the one before it, and the last note written.

Enums

Affinity

Which kind of grouping an element goes in, in the order a measure’s groupings are written: music21’s Affinity.

Hand

The hand a keyboard part is played by.

Functions

affinity_code

The affinity braille groups an element by and the order it sorts in among elements at its place, nothing for one braille does not write: music21’s setAffinityCode.

extract_braille_elements

The elements of a measure or voice braille writes, clefs before the note they stand before, sorted by offset and braille’s sort order: music21’s extractBrailleElements.

find_segments

A part’s segments, each told its options, its groupings their attributes and its articulations fixed: music21’s findSegments.

get_raw_segments

A part’s measures cut into segments of groupings: music21’s getRawSegments. A segment ends after a double or final barline once it holds more than 48 elements.

prepare_beamed_notes

Marks the notes of a measure that begin and continue a beamed group of three or more notes of one value shorter than an eighth, which braille writes as eighths after the first: music21’s prepareBeamedNotes. The marks go in contexts, by element.

prepare_slurred_notes

The slurs of a part as each note writes them, by leaf: short slurs after each note, long ones with brackets or doubled at their ends: music21’s prepareSlurredNotes.

split_note_grouping

A measure of groupings split in two at the middle of its bar, or nearer its start by beat_division_offset divisions of a beat, tied notes kept with the first half and each half beamed again: music21’s splitNoteGrouping.

transcribe_note_grouping

A grouping in braille from a fresh transcriber: music21’s transcribeNoteGrouping.

Type Aliases

KeyPair

The keys of a measure’s groupings for the right hand and the left, either missing where that hand has none.
