All notes and chord symbols here are written for B-flat trumpet. Written F7 sounds as concert E♭7, so choose a concert E♭7 backing track if you want to play these exercises with accompaniment. Over a concert F7 track, a B-flat trumpet player would instead use written G Mixolydian.
Use the octave from first-space F to top-line F:
| Written note | Valves |
|---|---|
| F, first space | 1 |
| G | Open |
| A | 1+2 |
| B♭ | 1 |
| C | Open |
| D | 1 |
| E♭ | 2+3 |
| F, top line | 1 |
Mixolydian is a major scale with a lowered seventh. F major contains E natural; F Mixolydian contains E♭. That E♭ is also the seventh of F7, making it an important target rather than just another passing note.
If top-line F feels strained, work between first-space F and third-space C first. Add the upper notes without increasing mouthpiece pressure.

Play this ascending and descending line in quarter notes:
F–G–A–B♭–C–D–E♭–F–E♭–D–C–B♭–A–G–F
Hold the final F for two beats. Rest for a full bar before repeating.
First, tongue every note lightly. Then slur pairs while maintaining the same pulse. Listen especially to D–E♭–F: coordinate the change from valve 1 to 2+3, then back to 1, so no extra note slips between them.
Complete three clean repetitions before raising the tempo by 5 bpm. If the upper register tightens, return to the lower five notes.
Play each group as four eighth notes, followed by two beats of rest:
Reverse each group on the next pass: B♭–A–G–F, then C–B♭–A–G, and so on.
Keep the first note clear without accenting it heavily. Begin with even eighth notes; try a relaxed swing feel only when the finger changes stay clean. The rests give you time to hear and prepare the next starting pitch.
Play F–A–C–E♭ as quarter notes, then descend E♭–C–A–F. Rest for one bar between repetitions.
The fingerings are:
F — 1, A — 1+2, C — open, E♭ — 2+3.
These four notes outline F7 without needing the entire scale. Give A and E♭ special attention: the third and lowered seventh identify the dominant-seventh sound.
For a simpler starting point, use the F major triad inversion drills, then add E♭ to each phrase.

Read the note and rhythm transcript below. Staff notation requires JavaScript.
Land on the third Straight initial reading; later swing variations remain in prose. Concert pitches in the transcript are references only; play the written pitches on B-flat trumpet. No audio playback or fixed swing ratio is implied.
In 4/4, play four eighth notes on beats 1–2, then hold the target as a half note on beats 3–4:
Rest for a bar after each phrase. Hear the target before you begin; avoid treating the held note as an afterthought.
Next, invent your own four-note pickups using only F Mixolydian. Keep A or E♭ as the destination. This makes the exercise about chord awareness, not simply running a scale.
Spend two minutes on the scale, two on four-note cells, two on chord tones, and two on target phrases. Rest whenever your response or tone deteriorates.
Use the JazzValve F Mixolydian practice screen as your note reference. Once these patterns feel comfortable, compare them with the C Mixolydian drills, keeping the same rhythmic shapes and chord-tone goals.
