music21.instrument

This module represents instruments through objects that contain general information such as Metadata for instrument names, classifications, transpositions and default MIDI program numbers. It also contains information specific to each instrument or instrument family, such as string pitches, etc. Information about instrumental ensembles is also included here though it may later be separated out into its own ensemble.py module.

Instrument

class music21.instrument.Instrument(instrumentName: str | None = None, **keywords)

Base class for all musical instruments. Designed for subclassing, though usually a more specific instrument class (such as StringInstrument) would be better to subclass.

Some defined attributes for instruments include:

• partId

• partName

• partAbbreviation

• instrumentId

• instrumentName

• instrumentAbbreviation

• midiProgram (0-indexed)

• midiChannel (0-indexed)

• lowestNote (a note object or a string for _written_ pitch)

• highestNote (a note object or a string for _written_ pitch)

• transposition (an interval object)

• inGMPercMap (bool – if it uses the GM percussion map)

• soundfontFn (filepath to a sound font, optional)

Instrument methods

Instrument.autoAssignMidiChannel(usedChannels: list[int], maxMidi=16)

Assign an unused midi channel given a list of used channels. Music21 uses 0-indexed MIDI channels.

assigns the number to self.midiChannel and returns it as an int.

Note that the Percussion MIDI channel (9 in music21, 10 in 1-16 numbering) is special, and thus is skipped.

>>> used = [0, 1, 2, 3, 4, 5, 6, 7, 8, 10, 11]
>>> i = instrument.Violin()
>>> i.autoAssignMidiChannel(used)
12
>>> i.midiChannel
12

Note that used is unchanged after calling this and would need to be updated manually

>>> used
[0, 1, 2, 3, 4, 5, 6, 7, 8, 10, 11]

Unpitched percussion will be set to 9, so long as it’s not in the filter list:

>>> used = [0]
>>> i = instrument.Maracas()
>>> i.autoAssignMidiChannel(used)
9
>>> i.midiChannel
9

>>> used = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
>>> i = instrument.Woodblock()
>>> i.autoAssignMidiChannel(used)
11
>>> i.midiChannel
11

If all 16 channels are used, an exception is raised:

>>> used2 = range(16)
>>> i = instrument.Instrument()
>>> i.autoAssignMidiChannel(used2)
Traceback (most recent call last):
music21.exceptions21.InstrumentException: we are out of midi channels! help!

Get around this by assinging higher channels:

>>> i.autoAssignMidiChannel(used2, maxMidi=32)
16
>>> i.midiChannel
16

• Changed in v.9 – usedChannelList is required, add maxMidi as an optional parameter.

  various small tweaks for corner cases.

Instrument.bestName()

Find a viable name, looking first at instrument, then part, then abbreviations.

Force a unique id by using an MD5
