I’m an amateur jazz guitarist, and although I usually play from Realbook
leadsheets I occasionally need to produce my own.
Typically, I want PDF output in three files, (Concert pitch, Bb and Eb), and I
would like to modularise this as much as possible.
The .ly code which follows shows what I’m trying to do, but there are a couple
of problems I would like help with.
1. I’d like to define a variable (\BaseFileName) which is the name of the song,
and have this variable picked up for the title in the header, and when I’m
creating the three PDF files with the relevant instrument names appended.
e.g. "Generic (guitar).pdf”, “Generic (trumpet).pdf” and “Generic (alto).pdf”.
2. The LilyJazzText font uses small capitals instead of lower case letters, so
using “Eb” produces a capital E followed by a small capital B. On my Mac I know
how to produce a flat sign, and LilyPond will use the flat sign from another
font, but I’d like to be able to define a flat sign as a variable, and append
it to the piece markup when creating the books for trumpet and alto.
Thanks in advance,
Michael Hendry
