- NOTE: the term “inversion”, in this case means something different than
the inversion of intervals or the inversions of chords.
- The inversion of a motive is another motive that does the opposite (example,
if the motive ascends by step, its inversion would descend downward by step)
- The augmentation of a motive would be to use the same pitches of the original
motive, but the rhythm of each pitch would be lengthened, usually keeping the same
ratio to the original (example, a motive with 2 quarter notes and an eighth note
might have the augmentation of 2 half notes and a quarter note)
- The diminution of a motive would be to use the same pitches of the original
motive, but the rhythm of each pitch would be shortened, usually keeping the same
ration to the original (example, a motive with 2 quarter notes and an eighth note
might have the diminution of 2 eighth notes and a sixteenth note)
- Extending a motive means to add a little bit of additional material to
the original motive
- Truncating a motive means to subtract a little bit of material contained
in the original motive
