Aha, of course.  Anyway, we'll leave that for later/a guitarist.

I'll teach her.  It seems the n+ n- is kind of a standard, so we'll
use that for entry, at least.

That standard says C5+ /C5- for Caug Cdim, resp.  And thinking a bit
further, we could drop the min/m too: Cm -> C3-

Or one of these (urg):

  C7j Cmaj7 Cj7 C7\neutral C7# C7+ C7\delta

It seems that 'maj7' has started to live a life of its own.  It would
be good to drop 'maj' too.

Ok, shorthands are for later, maybe.

Ok.  I do see some C4 too (and indeed C6, but never C2.

Ok, what about '^' iso 'no': 'c^3', 'c9^7'?

Another nasty shorthand.  Would "C4^3" do?

Would this be acceptable/good enough/convenient for entry?

   Convention/Standard    Logical/Lily(?)
   
   C#                     cis

That'll do, translating perl->c++ will be harder than PS->TeX, i guess.

My idea exactly.

On my way home i bought:

  Harald Banter
  Akkord Lexikon
  Schott's S"ohne, Mainz 1982.
  ISBN 3-7957-2095-8

  [At first glance it seems a] Comprehensive overview of commonly used
  chords.  Suggests (and uses) a unification for all different kinds
  of chord names.
