A4 Trumpet Fingering
How to play A4 on the trumpet: Valves 1 + 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 A4 fingering, step by step
- Press valve 1 with your right index finger — press it straight down, all the way, with the pad of the finger.
- 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: valves 1 + 2 pressed.
Alternate fingering for A4
Valve 3 pressed.
Valve 3 alone is the standard substitute for 1+2, drawn on Yamaha’s chart. It is often smoother in a slurred line and can sit truer in tune.
About A4 on the trumpet
The middle register mostly repeats the low register’s combinations an octave of harmonics higher — F♯4 is valve 2, just as B3 is. The exception is the top of the staff, from C♯5 onward, where the harmonics crowd together and the fingerings shrink: C♯5 is 1+2, D5 is 1, E♭5 is 2 and E5 is open.
A4 is note 16 of the 31 in the full trumpet fingering chart, sitting between G♯4 below it and B♭4 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 A4
If this note comes out an octave or a fifth away from where you aimed, the valves are rarely the problem — your lips found the wrong harmonic. Sing or hum the pitch first, then play it; the fingering only works once the right partial is in your ear.
