Re: question about transposing an interval of a 4th

[Gilles THIBAULT]

I didn't follow all the thread but coming back to the original message, I 
have tried to make a little scheme function which seems to work. (see
attached file)
It can be also usefull  for changing the mode of a music (major to minor for
example).

Merry Christmas.
