The three most important notes on a D whistle: B, A, and G. These are the foundation of almost every Irish tune.
Cover only the first hole (top, closest to your mouth). Leave all five lower holes open. This is B.
Blow gently — it should sound clear and bright. B is one of the easiest notes on the whistle.
Cover the first two holes (top hand index and middle fingers). Leave the remaining four holes open. This is A.
A is the most common note in Irish music. Practice switching between B and A smoothly.
Cover all three holes of your top (left) hand — index, middle, and ring fingers on holes 1, 2, and 3. Bottom hand stays off. This is G.
G is the lowest note in this set and requires a slightly gentler breath.
Play this simple pattern to build muscle memory:
Repeat slowly, focusing on clean transitions. Each note should speak clearly without squeaks between changes.
