Re: do these notes exist?

[Ledocq-Boccart]

Hi Maarten, Hi List,

I also feel almost silly to give you what follows.

This should be a theoretical matter , just for correct writting of a 
major scale according to its definition,  i.e. "has to be diatonic" in 
its writting.

I have already seen such things while learning accordion bass keyboard 
(left hand) configuration:

Have a look on

http://www.red-bean.com/noel/keyboard-layouts/basses/stradella-120.gif

on the grey button on right side of the image, two buttons are noted F* 
and C*,  for F## and C## (ie Feses and Ceses)
see also at left side a black button noted Bbb ( = Bisis)

on accordion bass keyboard, buttons are sorted and noted according to 
the  following serie
Bbb Fb Cb Gb Db Ab Eb Bb F C G D A E B F# C# G# D# A# E# B# F## C##

I give you what I know with my words - sorry for my rather basic english 
knowledge or mistakes -
That is the continuation of the alteration serie (you know F C G D A E B 
if, starting from C major scale, the major scale "shifted" of 5 degrees 
above C gives the G major scale with Fes; and so on with D major scale 
with Fes + Ces; and so on up to 7 # with the Ces major scale);
going on with the Ges major scale (5 degrees above Ces) asks G - no 
alteration here -;
and 5 degrees above Ges gives Des major scale asking D as alteration;
the Des major scale written " Des F Fes ...C D" "sounds" correctly; but 
that notation does  not  fullfill the definition of the "diatonic" major 
scale (which requires diffrerent names for notes).

That should be why - as far as I know - "Des Ees Fes ... Bes *Ceses*" 
should be the correct writting of the Des major scale.

(...rather theoratical, is not it?)

Same explanation for Bisis in the reverse direction.

Sorry for eventual ... headaches  ;-)

Charlie
