The first note you will learn to play is the B note shown in the previous diagram. Place your fingers in position to play the note and put the tip of the mouthpiece into your mouth.
Use your lips to seal off any air from escaping out the sides of your mouth and blow smoothly and steadily into the tin whistle. Don’t blow too hard or start the note too suddenly, or you may cause the note to sound at the wrong pitch or cause the instrument to squeak.
