[linux-audio-user] creating harmony files ( 3rd, 4th, 5th)

I never had any musical formation classes whatsoever, but I believe that
using a pitch stretch technique it would give you notes 'offscale'. for
instance, you have the C major scale; if you want the 3rd of C, it would be
exactly 4 semitones above (E) but the 3rd of D it would be 3 semitones above
(F) for the 3rds to be in scale...
I know guitar pedals have somehing called 'harmonizer' where you can define
in which scale you are playing, and it gives you the 3rd, 4th, whatsoever on
that scale...

Hope that helped...
