music21.tree.toStream

Tools for generating new Streams from trees (fast, manipulable objects)

None of these things work acceptably yet. This is super beta.

Functions

music21.tree.toStream.chordified(timespans, templateStream=None)

DEPRECATED – DO NOT USE. Use stream.chordify() instead.

Creates a score from the PitchedTimespan objects stored in this offset-tree.

A “template” score may be used to provide measure and time-signature information.

>>> score = corpus.parse('bwv66.6')
>>> scoreTree = score.asTimespans()
>>> chordifiedScore = tree.toStream.chordified(scoreTree, templateStream=score)
>>> chordifiedScore.show('text')

DEPRECATED in v7 – use chordify()
