Cuts, taps, rolls and the rest: how they're written, how they're played, and how they sound
Each one is played plain first, then ornamented, so you can hear the difference. Slow it right down to hear what's going on inside an ornament. Grace notes are so quick they barely have a pitch: you hear them as a flick or a bump in the note, not as a tune. The ornaments here are in D major on whistle and flute and on the fiddle's A and E strings; they work the same way in any key.
