... and then a music function inspired by those that figure string-number
for tablature to generate the false-pitches for scordatura.

On the other hand, the existing sources are manuscripts written in 
false-pitch, so writing a function to convert from false-pitch to true-pitch
would make initial entry easier.  There are some tricks required either way.

Since staff-positions correspond to scale steps one-to-one, a natural
LilyPond kind of pseudo-scordatura would have the staff lines and ledger 
lines at un-equally-spaced positions -- distorting the staff lines to 
represent the tuning but leaving the note-head positions alone.
