Play a full written C-to-C chromatic octave with clear valve fingerings, then turn those half steps into a short jazz approach-note exercise.
I focus on E♭–E on my B-flat trumpet, keeping the second valve down while the first and third fingers exchange positions. I listen for a clean half step rather than a brief extra pitch between the notes.
This chromatic scale trumpet finger chart starts with the change I listen for first: open C to low C♯, where the sound can stumble.
All three valves go down. The resistance changes. Your air still needs to carry the line. I’d rather hear thirteen steady quarter notes than a fast octave with a dent in the middle.
Grab your B-flat trumpet and set a pulse at 60 BPM. Play upward, then reverse direction without rushing.
These are written trumpet pitches, not concert pitches. On a B-flat trumpet, written C sounds concert B-flat. Low C here means C4, one ledger line below the treble staff. The upper C is C5, in the third space.
Valve 1 is nearest your mouthpiece. Valve 3 is nearest the bell. Open means no valves pressed. 1–2 means press both valves together.
| Written note | Staff location | Valves | |---|---|---| | C4 | Ledger line below staff | Open | | C♯4 / D♭4 | Below staff | 1–2–3 | | D4 | Below staff | 1–3 | | D♯4 / E♭4 | Below staff | 2–3 | | E4 | First line | 1–2 | | F4 | First space | 1 | | F♯4 / G♭4 | Second line | 2 | | G4 | Second line | Open | | G♯4 / A♭4 | Second space | 2–3 | | A4 | Second space | 1–2 | | A♯4 / B♭4 | Third line | 1 | | B4 | Third line | 2 | | C5 | Third space | Open |
The staff-location column follows the flat spelling wherever two names appear. F♯ sits in the first space; G♭ sits on the second line. They sound alike here and share a fingering.
Likewise, D♯ sits below the staff while E♭ sits on the first line. G♯ uses the second line; A♭ uses the second space. A♯ uses the second space; B♭ uses the third line. Accidentals change pitch, not the staff position of the letter name.
For valve basics, I’d start with Fingering for the Trumpet: A Practical Jazz Guide.
Open JazzValve Practice, keep this chart beside you, and play C4–C5 in quarter notes. Take a breath whenever you need one.

Use this chromatic scale trumpet finger chart in three groups:
Tongue each note lightly. Then slur each group. Breathe between groups rather than squeezing out the last note.
Low C♯ can feel more resistant than open C. Don’t answer with extra mouthpiece pressure. Low C♯ and D also tend to run sharp with their standard fingerings. Extend your adjustable third-valve slide as needed, checking against a tuner. There’s no universal slide distance.
I listen closely to E♭–E. Keep valve 2 down while releasing valve 3 and pressing valve 1 together. A mistimed swap puts an unwanted note in the gap.
The F♯ is another checkpoint. Moving from F to F♯ means releasing valve 1 while pressing valve 2. Keep both motions small. Your fingers don’t need a running start.
Start at 60 BPM, or slower. I only raise the tempo when the changes stop announcing themselves.
1. Minute one: ascend in quarter notes, breathing as needed. 2. Minute two: descend C–B–B♭–A–A♭–G–G♭–F–E–E♭–D–D♭–C. 3. Minute three: repeat E♭–E and F–F♯ slowly, four times each. 4. Minute four: play overlapping four-note groups as even eighth notes. Rest between groups. 5. Minute five: try the approach-note exercise below.
If a note cracks, repeat the surrounding three notes softly. Valves choose tubing lengths; your air and embouchure still select the register.
Head to JazzValve Practice for your next practice block. Follow the five-minute plan above, keeping your fingertips close to the buttons.

A scale gives you motion. I want you to hear a destination, too.
Play D♯–E, F♯–G, B–C using 2–3 → 1–2, 2 → open, and 2 → open.
Put each approach note on beat four. Land on its destination on beat one and hold for two beats. E, G, and C belong to a written C major triad.
Listen to Clifford Brown on Study in Brown, especially “Joy Spring,” for chromatic movement inside clear melodic phrases. This exercise isn’t a transcription. It’s a small way to practise making tension lead somewhere.
Open C major triads for the target-note framework. Keep the chromatic scale trumpet finger chart nearby and finish with the three approach pairs.
