Dear Luca,

this is a question you should ask on the lilypond-user mailing list.
I have forwarded it there but I strongly suggest you subscribe at https://lists.gnu.org/mailman/listinfo/lilypond-user to automatically receive any replies.

Hello,
I've been using lilypond for a little while now and I rather like it.

I've been able to achieve most of what I want for my engraving needs, but I think I need some help to set up slash chords like in this example

http://www.apianotuner.com/img/RealBookSample.gif

I'm using the font "New Real Book Chords" distributed here https://musescore.org/node/7785, and I have setup exceptions to the Ignatzek rules to drive the font correctly, but I can't find a way to tell lilypond that the bass note should be set lowered (like in the gif above).

I have put a small repro case at the bottom of this message

Any help or indication you could spare would be greatly appreciated (I am a fairly accomplished software engineer and I'm not afraid of writing code to achieve this, although I have to confess I am a C++ guy, not a Guile/Scheme guy).

Thanks very much
Luca Fascione
