Re: SacredHarpHeads: possible solution to major/minor problem

[Ted Walther]

I think it is fair to say that in older Sacred Harp music, there are
never accidentals.  But they do happen occasionally.  It it is only in
minor keys that the 6th degree is raised half a step without the
accidental reporting it.

Btw, great Scheme hackery, I knew there must be something like that!

Mark, could I pay you $100 to implement something that fits the bill for
sacred harp minor keys?  If we need to negotiate, let's do it in private
email.  The major keys are as normal.
