Concert Pitch Relationship
A B♭ trumpet is a transposing instrument pitched in B-flat: every note sounds a Major 2nd (2 semitones / 1 whole step) lower than written. Written C5 sounds as Concert B♭4 (466.16 Hz), and written D4 sounds as Concert C4.

Tune your main tuning slide to Concert B♭4 (written C5, Open 0) without lipping the note up or down, then verify Concert F4 (written G4, Open 0). Always extend the 3rd valve slide on written D4 (1-3) and C♯4 (1-2-3).
Instant conversion between Concert Pitch (piano, flute, trombone) and Written B♭ Trumpet pitch, with valve fingerings & key signatures.
| Concert Pitch (Piano) | B♭ Trumpet (Play) | Valves | Audition |
|---|---|---|---|
| C/ B♯ | D | 1 - 3 | |
| D♭/ C♯ | E♭/ D♯ | 2 | |
| D | E | 1 - 2 | |
| E♭/ D♯ | F/ E♯ | 1 | |
| E/ F♭ | F♯/ G♭ | 2 | |
| F/ E♯ | G | 0 | |
| F♯/ G♭ | G♯/ A♭ | 2 - 3 | |
| G | A | 1 - 2 | |
| A♭/ G♯ | B♭/ A♯ | 1 | |
| A | B/ C♭ | 2 | |
| B♭/ A♯ | C/ B♯ | 0 | |
| B/ C♭ | C♯/ D♭ | 1 - 2 |
Always transpose UP one whole step (Major 2nd) and add 2 sharps (or subtract 2 flats). For example: Concert B♭ becomes Trumpet C (Open).
When sightreading directly from a C score or hymn, imagine every note shifted up one line or space on the staff, adding two sharps to the key signature.
When your conductor asks the band to tune to “Concert B♭”, play your written C. For “Concert F”, play your written G.
