Oh right yes I understand your point indeed!

Yes and unless one has an instrument designed to repeat at
the tritave too e.g. with same fingerings for notes a tritave
apart or something then it is going to be easier for a
performer to read from an octave based score even though the
scale is tritave based.

I wonder if you anyone has designed an instrument
that is designed with the aim of overblowing
at the tritave, indeed designed about the
Bohlen Pierce scale perhaps.

There's one note on the recorder,
the a high c'' on the treble which
I think is a natural tritave above
the middle range f' - it is played
like the f'' but with much stronger
breath pressure and tonguing and
is used in one of Teleman's recorder
sonatas as perhaps the highest pitched
early music recorder note (relative to the
instrument range). It is used at a
point of emphasis not suprisingly - it would
be quite hard (perhaps not quite impossible)
to play it softly and gently..

You can also get it
with a bit more difficulty on a
descant as a high g''' - which is perhaps
about the highest note you can play
that still sounds reasonably musical though
there is an a''' above it that is also
quite decent.

It makes sense now anyway. Thanks.

Yes, and I can safely say that the inventor *didn't* have the BP
scale in mind: It's called a clarinet.

Robert, most of the other things requiring my reply would probably
best be done off-list, since they pertain mainly with the
implementation of Sagittal in FTS.
