Concert Pitch Relationship
The C Trumpet is non-transposing: written C4 sounds directly as Concert C4 (261.63 Hz), and written A4 (Valves 1-2) sounds directly at Concert A = 440 Hz.
INSTRUMENT-SPECIFIC CONFIGURATION
Slightly shorter and brighter than the B♭ horn, the C Trumpet is the primary instrument of American and European symphony orchestra sections.
Non-transposing concert pitch (Written C4 = Concert C4)
Standard Concert B♭4 band tuning note — zero slide offset
Why use Alt (2 - 3): 5th-partial alternate for B–C trill
Primary band tuning pitch (Concert B♭4). Spin fast, relaxed air through center of bell.
The C Trumpet is non-transposing: written C4 sounds directly as Concert C4 (261.63 Hz), and written A4 (Valves 1-2) sounds directly at Concert A = 440 Hz.
Standard choice for Mahler, Brahms, Strauss, Debussy, Ravel, Stravinsky, and sacred/choral chamber repertoire alongside piano or organ.
Because C trumpets have shorter overall tubing (~120 cm vs ~148 cm on B♭), intonation tendencies on 5th-partial E5 (0) and 4th-space E♭5 (2 vs 2-3) are more pronounced—audition alternate fingerings carefully with a tuner.
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.
