Hi Sorcha. In the sheet music, the final note is a D that's on the second line from the top in the treble clef, with the harmonic symbol. The harmonic-signal A (on the second space from bottom) is the second last note.

Speaking from memory of hearing it performed, I'm pretty sure that the last note should sound higher than the second last note. If I did a harmonic in the middle of the D string, that would be a fourth lower than the harmonic in the middle of the A string, wouldn't it? Though as Jon said, it would be a reasonable compromise note.

You're probably right that the D harmonic on A string I described is physically impossible - I don't have a fiddle in front of me to check it out. So maybe what I'm really supposed to do is fret an octave-up D on the D string, then do a harmonic touch halfway between that octave point and the bridge? That would be less of a stretch, and would presumably produce a D pitched two octaves above the open D?

Thanks very much for the discussion - I think I may have it now. In theory, anyway.
