C2 Tuba Fingering
How to play C2 on the tuba: Valves 1 + 3 pressed. — on the 3rd partial, in bass clef, sounding exactly as written.
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. These are three-valve fingerings for the BB♭ tuba; the staff is in bass clef, and in bass clef the tuba sounds exactly as written. The same fingering serves the sousaphone.

The C2 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. Half-pressed valves leak, and on a tuba a leak means a gargly, unfocused note.
- Press valve 3 with your right ring finger — press it straight down, all the way, with the pad of the finger. Half-pressed valves leak, and on a tuba a leak means a gargly, unfocused note.
- Keep the fingers you are not using curved and resting lightly on their valve caps, ready for the next note.
- This combination (valves 1 and 3 together) runs sharp on a three-valve tuba, because two shorter valve slides added together always come up short. Lip the note down a little, or pull the first valve slide — and if your tuba has a fourth valve, this is exactly the fingering the fourth valve replaces: play valve 4 alone instead.
In short: valves 1 + 3 pressed.
About C2 on the tuba
The low register runs from the 2nd partial (B♭1, open) through the 3rd partial’s ladder (B1 up to F2). These notes want a large, slow, warm column of air and a relaxed, wide buzz — a tuba is not blown harder down here, it is blown bigger. The two longest combinations, C2 and B1, play sharp and need the slide pull or the lip to bring them home.
C2 is the other half of the sharp pair: valves 1+3, the combination the fourth valve exists to replace. Four-valve players simply play valve 4 here. Three-valve players pull the first valve slide and lip it down — build that into the fingering from the start.
C2 is note 3 of the 25 in the full tuba fingering chart, sitting between B1 below it and D♭2 above it. Like every fingering on this site, it was checked against Yamaha’s official chart and the NoteAtlas tuba chart before publishing.
Practising C2
Low notes speak with slow air and an open throat — think of fogging a window on a huge scale. If this note cracks upward, your lips found the partial above: drop your jaw, slow the air down, and let the note settle rather than pushing it.
Questions about C2
What is the fingering for C2 on tuba?
Valves 1 + 3 pressed. C2 is played on the 3rd partial (harmonic) of the BB♭ tuba in the low register, with the three-valve fingerings this site charts. The full step-by-step is on this page, and you can hear the note with the Fingering Finder.
Does C2 sound as written on tuba?
Yes. In bass clef the tuba is a non-transposing instrument, so written C2 sounds as concert C2 — the same pitch a piano plays. The same fingering also serves the sousaphone, which is a BB♭ tuba wrapped for marching.
Is there an alternate fingering for C2?
For C2, the fingering above is the one to learn. It is the basic fingering both reference charts give for this note, and the one teachers expect to see.
