Here’s a nice tune to mark the quarter-century. I learned the first three parts of this from a Geraldine Cotter whistle tutor CD (don’t waste your money on that one) and the fourth part from Sharon Shannon’s Out the Gap. The first part was really hard until I learned to cross my third finger under my second to get the B on the left side. All the notes of the ascending arpeggiated bit in the fourth part are available on the push, but I am stubbornly refusing to abandon my base scale to play them that way.
