Rules

1. Your embouchure must remain firm and set throughout the exercise.
2. Breathe in tempo on beat 4, closing your lips at the top of the breath. You must be prepared to play any pitch.
3. A random pitch will be displayed on the "and of four." Play this pitch on the next beat for a full crotchet.
4. Remove the instrument from your face on beat one, keeping your embouchure firm and set.
5. Repeat.

Tips

• Practise with a mixture of "breath attacks" (no tongue) and traditional (tongued) entries.
• Practise on the mouthpiece alone with the reference pitch turned on.
