'transposition' is the literal one — every interval preserved, which is what
makes a sequence built on it a real sequence. 'tonalTransposition' shifts
by scale degrees instead and lets the key resize the intervals, which is what
makes a sequence built on it a tonal sequence; the two are different devices
and are never reported as one. 'augmentation' and 'diminution' name the
relation only when the pitches are untouched, so an inversion in doubled note
values reads as 'inversion' with a timeRatio of 2 rather than losing the
inversion to the stretch.
How one statement of a motif stands to another.
