Re: idea for fretboard-diagram chords

[bart deruyter]

hi,

I think things like adding \set chordShape #a would only be good in barré cases. 

I suggested the string as basis because of all the chords that are not based on the basic chords, and in different positions as well, with a root on different strings, often found in Jazz. 

I've looked at the link Patrick showed. These are indeed based on basic chord shapes but again, these don't offer a solution for chords out of the basic chord shape range.

In the mean time, I'm already working on a list :-p, I'll put them on github when I've got something worth to look at :-)

grtz,

Bart

This is the basic idea of
https://github.com/Philomelos/lilypond-predefined-fretboards. Here are
some test files: https://github.com/Philomelos/lilypond-predefined-fretboards/tree/master/EADGBE/test.
