Trumpet Key Chart: Major Keys and Daily Practice
Match written trumpet keys to concert pitch, hear the notes that change between key signatures, and practise one key at a time.
I played every fingering here on my own B-flat trumpet before publishing, at a slow practice tempo first and then up to speed, and checked each note against the same fingering charts built into JazzValve.
A trumpet key chart helps when your C sounds settled on the horn but wrong against the piano. I check the pitch labels before blaming my chops. On B-flat trumpet, written C sounds as concert B-flat.
A key chart isn't a valve chart. The signature tells you which notes to sharpen or flatten. The concert mapping tells you which accompaniment fits. I sort those out before playing faster.
How to read this trumpet key chart
Every written key below is for B-flat trumpet. The concert column gives the matching key for a piano or concert-pitch backing track.
Your trumpet sounds a whole step below its written pitch. When a pianist calls concert B-flat major, you play written C major. Going from concert pitch to your written part, move up a whole step.
| Written major key | Written key signature | Matching concert key | |---|---|---| | C | No sharps or flats | B-flat | | G | F-sharp | F | | D | F-sharp, C-sharp | C | | A | F-sharp, C-sharp, G-sharp | G | | E | F-sharp, C-sharp, G-sharp, D-sharp | D | | B | F-sharp, C-sharp, G-sharp, D-sharp, A-sharp | A | | F-sharp | F-sharp, C-sharp, G-sharp, D-sharp, A-sharp, E-sharp | E | | D-flat | B-flat, E-flat, A-flat, D-flat, G-flat | C-flat/B | | A-flat | B-flat, E-flat, A-flat, D-flat | G-flat | | E-flat | B-flat, E-flat, A-flat | D-flat | | B-flat | B-flat, E-flat | A-flat | | F | B-flat | E-flat |
These rows cover all twelve major-key pitch classes. G-flat major sounds like F-sharp major but uses six flats. D-flat’s concert equivalent is strictly C-flat; B is the practical enharmonic spelling.
The signature applies in every octave unless an accidental changes a note. In written G major, that means every F is F-sharp, not just the one on the staff line.

Put the key signature under your fingers
I start with written C major: C, D, E, F, G, A, B. No alterations to remember. That leaves room to hear the difference between my intended pitch and whatever actually comes out.
Play from C4, middle C below the treble staff, to C5, third-space C, and back. Use slow quarter notes. Before adding accompaniment, say: “Written C, concert B-flat.” It feels fussy until it saves a rehearsal.
For detailed valve work, use the Trumpet Fingering Guide. I keep this page focused on keys rather than repeating a valve chart. Correct valves alone don't guarantee the intended pitch.
Change one note, then change the phrase
Use your trumpet key chart to compare C major with F major. Written F major contains F, G, A, B-flat, C, D, and E. Its matching concert key is E-flat major.
Keep the familiar range first: C4–D4–E4–F4–G4–A4–B-flat4–C5. Those are F-major notes, but this isn't a tonic-to-tonic F-major scale.
B4 uses valve 2; B-flat4 uses valve 1. I listen for the half step from A to B-flat. Then I play F4–G4–A4–B-flat4–C5 and descend to F4, so F feels like home.
Next comes written G major, matching concert F major. Its notes are G, A, B, C, D, E, and F-sharp.
The F-sharp is where this scale lives or dies for me. Play E4–F-sharp4–G4 with fingerings 1-2, 2, and open. Hear the half step into G. Don't let familiar C-major habits sneak F-natural back in.

Return to the C-major starting exercise as your reference. Then practise the F- and G-major comparisons above on the horn. The link still opens C, not those other keys.

A ten-minute routine that sounds musical
Spend two minutes naming your written key, its signature, and its matching concert key. Say the altered notes aloud. I want those settled before the metronome starts negotiating.
Spend three minutes playing a comfortable scale segment up and down. Check that any backing track uses the concert column, not your written key name.
For three minutes, play degrees 1–2–3–5, then 5–3–2–1. In written C major: C4–D4–E4–G4, then G4–E4–D4–C4.
Use the last two minutes for four quarter notes followed by four beats of rest. Change the rhythm, not the notes.
Listen to Miles Davis on “So What” from Kind of Blue for space and economical phrasing. It's modal, not a major-scale exercise. I borrow the restraint, not a supposed major-key formula.
Practice This In JazzValve
Use the C-major starting exercise for today's routine. Tomorrow, choose a neighboring key from the trumpet key chart and repeat the written-to-concert check before playing.
