Scales · September 22, 2026
By Justin James · Jazz trumpet player and founder of JazzValve · Updated September 25, 2026
Play written F Dorian with clear valve fingerings, short scale patterns, and a minor-chord improvisation drill for B-flat trumpet.
I focus on moving valves 2 and 3 together when connecting written G to A-flat on my B-flat trumpet. I listen for a clean connection rather than trying to hide an uneven valve change with a stronger tongue attack.
These f dorian scale trumpet exercises with fingerings start with one playable octave, then turn those notes into short minor-chord phrases. Grab your B-flat trumpet, set a metronome to 60 bpm, and begin with comfortable quarter notes.
All notes below are written trumpet pitches, not concert pitches. Written F Dorian sounds as concert E-flat Dorian on a B-flat trumpet. For backing tracks, choose concert E-flat minor seventh, not concert F minor seventh.

Written F Dorian contains F, G, A-flat, B-flat, C, D, E-flat, F. Its formula is 1–2–flat 3–4–5–6–flat 7.
The A-flat makes the scale minor. However, D natural gives it a brighter edge than F natural minor, which contains D-flat. Listen for that difference rather than treating Dorian as another fingering list.
Use this octave, from first-space F to top-line F:
| Written note | Staff location | Valves | |---|---|---| | F4 | First space | 1 | | G4 | Second line | Open | | A-flat4 | Second space | 2–3 | | B-flat4 | Third line | 1 | | C5 | Third space | Open | | D5 | Fourth line | 1 | | E-flat5 | Fourth space | 2 | | F5 | Fifth line | 1 |
Valve 1 is closest to your mouthpiece; “open” means no valves pressed. For a broader reference, keep the Trumpet Valve Chart: Written Notes and Fingerings nearby.
If top-line F feels strained today, stop at C5. You can still practice the lower patterns without forcing your range.
Exercise 1: climb, settle, return. Play each note below as a quarter note. Each group between bar lines fills one measure of 4/4.
| F G Ab Bb | C D Eb F | Eb D C Bb | Ab G F rest |
Use a light “doo” attack. Then repeat with two notes slurred and two tongued in each four-note group. Keep the final F relaxed, rather than dropping your air before it speaks.
On trumpet, the G–A-flat change can feel less smooth than it looks. You move from open valves to 2–3 together. If those fingers arrive separately, an unwanted pitch can interrupt the line.
Practice G–Ab–G–Ab slowly, using open–23–open–23. Keep your fingertips near the buttons and move both valves together. The goal is an even connection, not a harder tongue attack.
These f dorian scale trumpet exercises with fingerings should sound connected before they sound fast. Increase the tempo only when the valve changes stop disturbing the pulse.

Exercise 2: four-note windows. Play one group per bar as quarter notes:
| F G Ab Bb | G Ab Bb C | Ab Bb C D | Bb C D Eb | C D Eb F |
Breathe after any bar when needed. Then reverse the direction:
| F Eb D C | Eb D C Bb | D C Bb Ab | C Bb Ab G | Bb Ab G F |
Keep every note within the octave in the chart. In the descending line, the first F is top-line F; the last is first-space F.
Exercise 3: hear the Dorian color. Repeat this two-bar phrase:
| F Ab C D | Eb D C rest |
Its valves are:
| 1 23 open 1 | 2 1 open rest |
D natural is the important color here. Sustain it briefly outside the exercise, then move to E-flat and back. Listen for the half step between D and E-flat.
Avoid accidentally playing D-flat with 1–2–3. That changes the scale’s character. Also, keep the air moving through C–D; pressing valve 1 alone does not guarantee the higher note will speak cleanly.
Over written Fm7, the chord tones are F, A-flat, C, and E-flat. Start or finish on these notes to make your improvisation sound settled. Then use G, B-flat, and D as connecting colors.
Try this call-and-response drill over a concert E-flat minor-seventh backing:
F Ab C D as four quarter notes.Eb C Ab F as four quarter notes.For a modal listening reference, hear Miles Davis on “So What” from Kind of Blue. The recording is not in written F Dorian. Listen instead for short statements, space, and how phrases avoid sounding like uninterrupted scale practice.
For a contrasting minor sound, explore the F Blues Scale Trumpet Fingerings and Practice Drills. Notice how its notes differ from Dorian rather than swapping scales automatically.
Finish these f dorian scale trumpet exercises with fingerings by opening JazzValve’s F Dorian scale screen. Play written F–G–A-flat–B-flat–C–D–E-flat–F upward and downward, then repeat F–A-flat–C–D–E-flat–D–C with one beat of rest.
