Thanks for the help ! On my computer, I use Linux Ubuntu 16.04. When you get Frescobaldi from the Ubuntu repository, it comes with Lilypond 2.18.2. I've not heard about the OpenLilyLib auto-transpose snippet. Where to get it or how to use it. I'll do some more research into that. Thanks. So, from Torsten's comments, see how this looks:
First, get the F trumpet some key signatures. Concert Ab puts the F trumpet in Eb. Later in the movement ( not shown in the ex: ) when the concert pitch changes to C then back to Ab, add the key commands for those: to G and back to Eb. Then use the transpose command to get notes and key signature for the Bb trumpet. \score { \transpose ees bes { \relative g' { \time 2/4 \key ees \major g8[-.\p g ( aes ) aes] ( g g4 ) g8 ( f ) f4 f8 ( g\<[ ) g ( f\> ees]\! ) d4 ( c bes2 ) \bar "|." } } } By accident I came across another possible solution. \score { \transpose c g { \relative g' { \time 2/4 g8[-.\p g ( aes ) aes] ( g g4 ) g8 ( f ) f4 f8 ( g\<[ ) g ( f\> ees]\! ) d4 ( c bes2 ) \bar "|." } } } This seems to work for the notes. Any reason not to do this ? Also there's no key signature. The effect is to transpose up 7 intervals.
