How would that affect the key signature that shows at the beginning of
each line?

How about a \sacredHarpKey that does the correct mapping etc?

In Sacred Harp music, the \sacredHarpHeads depends on the key you are
in.  Using Dorian would mess that up.

The way the different note-heads are used needs its own solution.
\dorian doesn't appear to be it.

By the way, instead of Scheme code, here is what I was using to set
sacredHarpHeads 3 years ago:

For the major keys, this definition works:

sacredHarpHeads = \set shapeNoteStyles = ##(fa #f la fa #f la mi)

But for minor keys, this definition must be in place:

sacredHarpHeads = \set shapeNoteStyles = ##(la mi fa #f la fa #f)

But that doesn't address the accidental issue at all.

Neil, are you up to making some sacred harp major and minor keys that
supress the accidental?

There must be a way in the scheme code to suppress the accidental!!!
