Hello, skarpi. I'm interested in the song, and I'm making a MIDI of the version on YouTube. (Search for Altan the wind and the rain.)

It's in the key of D. It's pretty low - the singer is an alto. The first three syllables ("there were two") seem to be pick-up notes.

I have to leave the mudcat and to take a friend to the doctor. I'll be back later today, so I hope you check later on to see what I've figured out.

I think this would make a nice flute tune as well as a ballad.
