How do you finger a low f on trumpet?

1. Hold the trumpet with your right hand and place your left hand on the valves.

2. Press down on the first valve (closest to your face) with your left index finger.

3. Simultaneously, press down on the second valve (in the middle) with your left middle finger.

4. Finally, press down on the third valve (furthest from your face) with your left ring finger.

5. Blow air through the mouthpiece and hear the low F note!
