music21.expressions

This module provides object representations of expressions, that is notational symbols such as Fermatas, Mordents, Trills, Turns, etc. which are stored under a Music21Object’s .expressions attribute

It also includes representations of things such as TextExpressions which are better attached to the Stream itself.

TODO: replace .size with a string representing interval and then create interval.Interval objects only when necessary.

Functions

music21.expressions.realizeOrnaments(srcObject)

given a Music21Object with Ornament expressions, convert them into a list of objects that represents the performed version of the object:

>>> n1 = note.Note("D5")
>>> n1.quarterLength = 1
>>> n1.expressions.append(expressions.WholeStepMordent())
>>> expList = expressions.realizeOrnaments(n1)
>>> st1 = stream.Stream()
>>> st1.append(expList)
>>> st1.show()

TextExpression

class music21.expressions.TextExpression(content=None)

A TextExpression is a word, phrase, or similar bit of text that is positioned in a Stream or Measure. Conventional expressive indications are text like “agitato” or “con fuoco.”

>>> te = expressions.TextExpression('testing')
>>> te.size = 24
>>> te.size
24.0
>>> te.style = 'bolditalic'
>>> te.letterSpacing = 0.5

TextExpression.content

Get or set the content.

>>> te = expressions.TextExpression('testing')
>>> te.content
'testing'
TextExpression.enclosure

Get or set the enclosure.

>>> te = expressions.TextExpression()
>>> te.justify = 'center'
>>> te.enclosure = None
>>> te.enclosure = 'rectangle'
TextExpression.positionVertical

Get or set the vertical position, where 0 is the top line of the staff and units are in 10ths of a staff space.

Other legal positions are ‘above’ and ‘below’ which are synonyms for 10 and -70 respectively (for 5-line staves; other staves are not yet implemented)

>>> te = expressions.TextExpression()
>>> te.positionVertical = 10
>>> te.positionVertical
10.0
>>> te.positionVertical = 'below'
>>> te.positionVertical
-70.0

>>> n1.quarterLength = 6
>>> n1.expressions.append(expressions.Fermata())
