GDP: 2.3.2.1 Harp

[Neil Puttock]

Hi everybody,

I've been looking through section 2, and noticed that the section on
harps mentions Sacred Harp music. Now I can't claim much knowledge of
old American choral traditions, but I'm pretty sure that it has
nothing to do with playing the harp.

Since there's no specific support for harps in LilyPond, do we need a
section dedicated to it?

Regards,
Neil
