Second, I would strongly advise against tuning a CBA or PA to anything but
equal temperament or very closely related to ET. Just intonation is not one
of those things. But the just intonation or Equal Temperament does not refer
to the musette tuning which relates only to a particular note on the
keyboard, not the harmonics between the notes on the scale, which would
change if the scale relationship were changed..

Ike, I completely agree with you. I went back and re-read what I had
posted on this, which was:

"And, finally, here's another consideration for you to think about: a
CBA accordion is tuned to Equal Temperament, just like a Piano
Accordion. A Diatonic Button Box, such as the Gabbanelli in the
video, may or may not be tuned to ET. Quite often they are tuned to a
"purer" temperament, called Just Intonation. It produces a "sweeter"
sound, however the accordion is then limited to the number of
different keys it can be played in. This may, or may not, be a big
deal if you talk about making your CBA sound "exactly" like that
Gabbanelli. Just something to keep in mind. You should have this
discussion with Gabbanelli, or perhaps the folks on the Reyes site."

I think perhaps I muddied the water, without quite making the point I
wanted to make, which is this: Retuning a CBA to sound like a
Diatonic Button Box might get you pretty close, particularly with
respect to the question of how wet the musette sound is, but it won't
duplicate the exact sound *if* the DBB has been tuned to a Just
Intonation. I agree with you that the CBA, or PA, should not be tuned
to a different temperament than ET, since they are intended to be
playable in all 12 keys.

Or, to put it more directly for Gino, if that Gabbanelli he likes has
been tuned to a Just Intonation (which it may have been since it is
only playable in 3 keys), his Hohner CBA will not be able to be tuned
to sound *exactly* like the Gabbanelli. This is why I recommended he
talk to the folks at Gabbanelli. They should know whether the
accordions they're selling have been tuned to Just Intonation or Equal
Temperament.
