Actually, sorry for not thinking about this before, but writing it in LaTeX gave me an idea to illustrate what I'd like to achieve (roughly).
%%%%%%%%%%%%%%%%%%%%%%%%%%
\version "2.18.2"
% test for setting slash chords with realbookchords font
chExceptionMusic = {
<c e g bes>1-\markup { "7" }
<c e g b>1-\markup { "<7/" \raise #-2.5 "B" } % for illustration purposes
only
<c ees g>1-\markup { ">" }
}
chExceptions = #( append
( sequential-music-to-chord-exceptions chExceptionMusic #t)
ignatzekExceptions)
\score {
\new StaffGroup <<
\chords {
\override Score.ChordName #'font-name = #"New Real Book Chords"
\set chordNameExceptions = #chExceptions
\set slashChordSeparator = "/"
f2.:m c4:7/e c2:maj7
}
\new Staff { \key aes \major \time 3/4 c'4 aes'2 c'4 bes'2 }
>>
\layout {}
}
%%%%%%%%%%%%%%%%%%%%%%%%%%
You can see I have hardcoded the form of Cmaj7 to render as Cmaj7/B, but
the spacing feels like a step in the right direction (admittedly the
kerning could use work, but it feels like a reasonable compromise)
I have attached the corresponding pdf I get, so you can see what I mean
Thanks,
Luca
