I'm getting started using lilyjazz to write Jazz-styled music. I'd like to get the Realbook-like notation that I'm used to featuring a triangle to denote a major seven.
the jazzchords.ily
stylesheet comes in pretty handy, but I'm struggling to find a proper substitution for the "M":
% for major chords, use "acMaj" to print a small "M"
#(define-markup-command (acMaj layout props extension) (string?)
(interpret-markup layout props
(markup #:super "M" #:super extension)))
Any suggestions?
