Re: Nested transposition

[Silvain Dupertuis]

I have nearly always used relative pitches.
I always use variables to build up the music in a logical way.
Transpose always worked right for me.

As for enharmonic transposition, it does work well
Here is an example :

 m = \relative c' { \key des \major des4 es f as des2. r4}

 \score {

   {

   \m

   \transpose des cis \m

   }

 }

There might be a way to write a function which would transpose in way so that
when transposing music with different keys,
if a part happens to have more than 6 or 7 flats or sharps
it will apply enharmonic transposition...
