Expand description
The features music21 ports from Cory McKay’s jSymbolic: music21’s
features.jSymbolic. Each is an Extractor in JSYMBOLIC, found
by its id with extractor.
The melodic features (M) read the intervals between neighbouring notes
of each part; the rhythmic features (R) read when each note sounds, in
seconds at the piece’s tempi, and its meters; the texture features (T)
read how many parts sound in each chord of the piece chordified; the
instrument features (I) read the piece partitioned by instrument and
each part’s General MIDI program; the pitch features (P) read the
piece’s pitches. Several
of music21’s habits are kept, since the values are the comparison: the
pitch variety (P8) counts the MIDI numbers sounding but MIDI nought, a
tie between two pitches equally common goes to the one sounded first, and
a melody with no arpeggiation at all (M8) is refused as one with no
notes.
