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

[Daryna Baikadamova]

Thanks for your help!  However I have three questions:

when we enter new scores, should we enter in concert pitch?

You suggested that it is not a good idea to use \displayLilyMusic because it only outputs absolute pitches, not relative, thus making the resultant score hard to maintain by humans.  However my situation is:
- the parts were not entered in concert pitch
- the parts are in pitches that are not common nowadays.  (e.g. in my score, trumpet in D, horn in E and clarinet in A, which I am afraid not many members in an (youth) orchestra will have.  Therefore I would also like to produce current transpositions in parts such as trumpet in Bb, horn in F and clarinet in Bb, or better, to produce pdf parts scores with different transpositions from one lilypond file.  What is the best way?

Would it be better for me to just annotate the original score (clarinet in A) by stating the transposition key of the instrument (\transposition), then for each version of parts, I use \transpose x y to transpose to the desired key in each case?

Or should I convert the score to concert pitch using \displayLilyMusic and then use \transpose x y in each case?

Thanks!

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 hope you have read http://lilypond.org/doc/v2.11/Documentation/user/lilypond/Transpose#Transpose
and
http://lilypond.org/doc/v2.11/Documentation/user/lilypond/Instrument-transpositions#Instrument-transpositions
which explain how to handle all these issues without rewriting the source file to concert pitch. Note also that the hint provided in a previous answer, of using \displayLilyMusic will result in absolute
pitches, not \relative.

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
