B3 Trumpet Fingering
How to play B3 on the trumpet: Valve 2 pressed. This fingering is the same on cornet and flugelhorn — only the tone differs.
Filled valves in the diagram are the ones you press. Valve 1 is nearest you and is worked by your right index finger, valve 2 by the middle finger, and valve 3 — nearest the bell — by the ring finger. The same diagram serves the cornet and flugelhorn charts, because all three instruments share these combinations.

The B3 fingering, step by step
- Press valve 2 with your right middle finger — press it straight down, all the way, with the pad of the finger.
- Keep the fingers you are not using curved and resting lightly on their valve caps, ready for the next note.
In short: valve 2 pressed.
About B3 on the trumpet
The low register is built as a chromatic ladder: the open harmonics (C4 above all) are lowered step by step by the seven valve combinations. This is where the system makes sense — valve 2 takes off a semitone, valve 1 a whole step, and the combinations add up exactly as the arithmetic says they should.
B3 is note 6 of the 31 in the full trumpet fingering chart, sitting between B♭3 below it and C4 above it. The same fingering serves the whole family — see it on the cornet fingering chart and the flugelhorn fingering chart too. Like every fingering on this site, it was checked against Yamaha’s official chart and the NoteAtlas valve chart before publishing.
Practising B3
Low notes need relaxed lips and slow, warm air — pressing the mouthpiece harder only thins them. If this note uses valves 1+3 or 1+2+3, build the third-slide movement into the fingering from the start: slide out as the valves go down.
