Dan, nice little tune, just checked it out. An A harp in Paddy Richter tuning would be perfect in my opinion, as Gary said. It gives you all the full chords to play accompaniment if you want (F#m would be 3-5 blow, but you can include 1 and 2 blow as well) and you have F# available as a natural note on 3 blow instead of the 3 draw hole tone bend. best wishes Hannes
