a script / tool for transposing a lilypond staff / source file by a given interval and output result as a new file

[Daryna Baikadamova]

Hi

I have received a symphony score, which parts are not typed in concert pitch.  This creates a problem when I want to create midi files for the score.  It also gives me some minor programming hassles when I want to create parts with a different transposition for my ensemble (e.g. the original score has clarinet in A, but my group only has clarinet in Bb.

I would like to clean up the source file by converting source files of transposing instruments back to their concert pitch and then use the '\transpose' command in their driver files to create transposed score.

Are there any existing tools which converts source files in this way?

Thanks

Daryna
