Ken, Using Trumpet in b-flat ... When the trumpet player looks at their part written in C-major and they play the note middle-c, c', what sounds is the note b-flat, one step lower. Thus all the orchestra/wind ensemble parts that play Concert C (your tuba or trombone) must play a b-flat to play the same note. Thinking at the score level, the work would be in the key of B-flat, but the part written for the b-flat trumpet will be in C-Major. This idea applies to all non-Concert
instruments. Following the example above with an F-horn part in
the key of C-Major. When the horn player plays middle C ( c' ),
the note that comes out is the F a fifth below c'. For the rest
of the concert-C instruments to play in the same key, they'd
play in F-Major. Now reverse the logic - a work in the concert key of C-Major. If the trumpet is a b-flat trumpet, and their C is b-flat, to get to concert-C they must play a whole step higher. Following the logic above, they'd be looking at their part in the key of D-major, and their note d' will sound one whole step lower, c'. You have several ways to proceed. One is to
enter the pitches AS THEY ARE in the score you have. Then use
the \transpose options in Lilypond to modify the output files:
To get a b-flat trumpet part to concert
pitch, its part must be written DOWN a whole step (from the
example above, from D-major in the trumpet part, to C-major
which is the key the work is in):
You can:
This can ALL happen in the \score {} part of your Lilypond source file:
If you enter the work in concert pitch, then the \transpose directive goes the other way. To get the output trumpet part for a work in concert C, the \transpose directive would be:

HI All; I have a couple downloaded examples of brass quartet arrangements (theme excerpts mostly) forn 8notes.com, hosted by UK composer David Bruce, where each part is apparently NOT in concert pitch, but the parts are together, as they would be in a conductor's score. The music, engraved as written, sounds AWFUL. I suspect that I need to run transpose on each part to convert them to concert pitch, but I don't know for sure if that's the case and if so, exactly how to do that. I have attached one example pdf to illustrate my question. I know, as an ex-tuba player (and a very low-level amatuer tuba player), that tuba and trombone (bassoon?) don't require transposition as they are already in concert pitch (I never played a tuba in the key of C, F or Eb). However most of the other wind instruments of an orchestra are not in concert pitch. So when there is a trumpet in Bb, it certainly is not the same as a tuba in Bb, correct? What about Horn in F? What happens when the overall pitch of the piece in question is not C Major? I've taken some church hymns, written for SATB (obviously) and converted them directly to a brass quartet (Soprano toTrumpet, Alto to French Horn, tenor to Trombone, and Bass to Tuba) and it doesn't sound bad, using the exact key the Hymn was written in. Could someone clue me in on the basics here (I've read the Lilypond manuals on this topic, but I think I need a more rudimentary explanation).
