Nice catch, I mixed the critturs together. Nonetheless, the
point was that some may consider a 3-step-size scale as being
from a parent 2-step-size scale (which I called diatonic)
if the Large stepsize is equal to the Medium + small.

I meant diatonic (as in 2-step-size). The diminished scale
isn't MOS is it? (Or else I've made hash out of another
perfectly good definition).

I didn't think so for a long time, but I've been set straight -- it
IS MOS. The 1/4-octave is the "period" or interval of repetition,
instead of the usual full octave.

It's very common in jazz and 20th century classical music . . . I've
mentioned that it's interesting in tunings such as 28-tET, where you
have _seven_ transpositions of the scale, as opposed to the only
_three_ you have in 12-tET . . .

Got it Paul, pretty sneaky.

This way of making the diminished scale MOS by treating the
1/4 octave as a cell is similar to what I saw in your scale
with the 318c cell.
