You're right. I followed the scoring given in 'Sources of Irish
Traaditional Music'. They don't give keynote, but with persistence with
their awkward notation ('Greek' modes un-named) one can figure out that
they took the keynote to be F#. I changed their Aeolian mode to Phrygian
to match key signature, but with C and G missing, 1, 2, or 3 sharps on
the key signature is all the same. The 2nd and 3rd don't do anything.
It's not uncommon the see a sharp or flat on the key signature for a
note that isn't in the tune.
Other versions there are usually noted as circular major. They also give
an alternate scoring for some of these as Phrygian scoring mode, but
with the 5th missing in that mode, and that's unlikely realistic. The
5th is hard to get rid of. It seems to be about the most stable note in
a tune.
You said what I think was probably the same as that, but I've lost your
posting where you said there might not be any pi-5 tunes. I'm going to
recheck my other two pi-5 to see if I got them wrong, too.
