Play written C major on B-flat trumpet with an octave-specific fingering chart, clean valve changes, and a short jazz phrasing exercise.
I focus on keeping valve 1 down through D–E on my B-flat trumpet, listening for a clean exchange between valves 3 and 2. I use A–B–C to approach the upper C rather than trying to force the open note.
This c scale trumpet finger chart gives you the written notes and valve combinations for one octave of C major on B-flat trumpet.
Start with C–D–E–F–G–A–B–C. Coming down, play C–B–A–G–F–E–D–C. Use a comfortable volume, and let each note speak before moving on.
The starting note is written middle C, on the ledger line below the treble staff. The top note is C in the third space. Because trumpet fingerings change across registers, these octave locations matter.
Valve 1 is nearest your mouthpiece, valve 2 is in the middle, and valve 3 is nearest the bell. Open means no valves pressed.
| Written note | Treble-staff location | Valves | |---|---|---| | C4 | Ledger line below staff | Open | | D4 | Space below staff | 1–3 | | E4 | First line | 1–2 | | F4 | First space | 1 | | G4 | Second line | Open | | A4 | Second space | 1–2 | | B4 | Third line | 2 | | C5 | Third space | Open |
C major contains no sharps or flats. Its half steps occur between E–F and B–C; all the other adjacent steps are whole steps.
For a quick first pass, play each note for two beats at 60 beats per minute. Breathe after G if needed. Then start again on A rather than squeezing out the final notes.
Keep your fingertips curved over the valve buttons. Press each valve fully, because a partly depressed valve can interrupt the sound.

This chart uses written trumpet pitch, not concert pitch. On B-flat trumpet, written C sounds concert B-flat. Therefore, this written C major scale sounds like concert B-flat major.
If a pianist asks for concert C major, your written scale is D major: D–E–F♯–G–A–B–C♯–D. That is a different exercise.
For today's practice, stay with written C. If you add accompaniment, choose concert B-flat major rather than concert C major.
This distinction also matters when learning recordings. A tune's concert key is not automatically the key printed in a B-flat trumpet part.
Use the c scale trumpet finger chart as a reference, but judge each change by your sound. Correct buttons alone do not guarantee the intended note.
C–D: Move from open to 1–3 together. If one finger arrives late, you may hear a brief unwanted pitch between the notes. Practise C–D–C, slowly and lightly tongued.
D–E: Keep valve 1 down while exchanging valve 3 for valve 2. This is a coordination challenge, so isolate D–E–D–E before repeating the whole scale.
E–F: Keep valve 1 down and release valve 2. Listen for a small half-step rise, not a sudden jump in volume.
B–C: Release valve 2 without adding a jab of air. The upper C should sound like an arrival, not a forced accent.
Both C notes and G use open valves, yet they occupy different resonances of the instrument. If G speaks instead of upper C, hear the target pitch first. Then approach it through A–B–C, without increasing mouthpiece pressure.
Low D with 1–3 often runs sharp. Check a sustained D against a tuner or drone. If your trumpet has a movable third-valve slide, extend it as needed rather than forcing the pitch down with your lips.

First, play these two bars as quarter notes:
| C4 E4 G4 A4 | G4 E4 D4 C4 |
The valve sequence is:
| Open, 1–2, open, 1–2 | Open, 1–2, 1–3, open |
This phrase starts with the C major triad, adds A, and returns home. Because the notes skip as well as step, it sounds less like a scale test.
Next, play the same eight notes as eighth notes in one bar. Follow with a full bar of rest. Keep the tempo at 60, and repeat four times.
For a swing reference, listen to Louis Armstrong's “When You're Smiling” recording from 1929. Notice how the melody has direction rather than equal weight on every note. This exercise is not a transcription; borrow that sense of forward motion.
Then explore C Major Triad Inversions: Trumpet Fingerings and Drills to develop the C–E–G shape.
Keep this c scale trumpet finger chart nearby for one final ascending and descending pass. Aim for even tone, coordinated fingers, and an unhurried upper C.
Open the JazzValve C major scale screen. Play C–D–E–F–G–A–B–C, then reverse it, using two beats per note at 60. Finish with C–E–G–A–G–E–D–C to turn the chart into a phrase.
