That F–A♭ valve change deserves a little time. I’ll show you written F blues fingerings, short drills, and how to choose a concert E♭ backing track.

For written F–A♭–B♭–B–C–E♭–F, use 1, 2+3, 1, 2, open, 2, 1 in the octave shown below. On B♭ trumpet, these notes sound as concert E♭ blues, not concert F blues.
Start on F4, the first space of the treble staff, and finish on F5, the top line. Valve 1 is closest to your mouth; valve 3 is closest to the bell. “Open” means no valves pressed.
| Written note | Staff location | Valves |
|---|---|---|
| F4 | First space | 1 |
| A♭4 | Second space, lowered | 2+3 |
| B♭4 | Middle line, lowered | 1 |
| B4 | Middle line | 2 |
| C5 | Third space | Open |
| E♭5 | Fourth space, lowered | 2 |
| F5 | Top line | 1 |
Ascending: F–A♭–B♭–B–C–E♭–F.
Descending: F–E♭–C–B–B♭–A♭–F.
The formula is 1–♭3–4–♭5–5–♭7. The lowered fifth is theoretically C♭. I use B natural here for easier reading. They sound the same and take the same fingering in this register.
F4 and F5 both use valve 1. Your fingers choose tubing lengths, not a single pitch. Listen for the octave before blaming the valve.
A B♭ trumpet sounds a whole step below its written notes. Here's the distinction I check before pressing play:
The chart sounds E♭–G♭–A♭–A–B♭–D♭–E♭ in concert pitch. General backing tracks usually name the concert key. A transposed trumpet part may name the written key. Check the label rather than guessing.

Open the blues screen with root=F — pitch convention unverified.
I can't verify whether this screen's root parameter means written or concert pitch. Don't treat the URL alone as a pitch label.
For this lesson, confirm that its written trumpet notes are F–A♭–B♭–B–C–E♭. If it provides accompaniment, confirm that accompaniment sounds in concert E♭. If either setting is unclear, use this chart with a separately labeled concert E♭ track.
Set your metronome to 60 bpm. Give each note two beats. Ascend once, rest, then descend. I listen for an even sound before increasing speed.
If upper F isn't comfortable, start with F–A♭–B♭–B–C. Add E♭ and F without squeezing.
These are the changes I isolate:
Tongue lightly first. Then slur pairs without interrupting your air. Practicing f blues scale trumpet fingerings means matching valve movement to sound, not just memorizing numbers.
Open JazzValve practice. Use the chart above as your reference for two slow passes. Rest between them. Keep the same tempo until the changes feel unremarkable.

Read the note and rhythm transcript below. Staff notation requires JavaScript.
Blue-note connection 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.
B natural is where I hear this scale's bite. Try:
B♭–B–C–B | B♭–A♭–F–rest
Fingerings:
1–2–open–2 | 1–2+3–1–rest
Play one item per beat across two bars of 4/4. Repeat softly, then give C a gentle accent. Hear B moving toward C or back toward B♭. Don't park on it just because it's the interesting note.
Now omit B: F–A♭–B♭–C–E♭–F. That's F minor pentatonic. I like hearing both versions back to back. The added half-step tension becomes obvious.
Use a concert E♭ blues track with these written F blues notes. Start with F, A♭, and C. Play a short phrase, leave a bar empty, then answer with a different rhythm.
Add B♭ and E♭ next. Bring B in as a passing note. I treat the scale as a palette, not attendance roll.
Listen to Miles Davis on “Freddie Freeloader” for phrase length and space, not as this exercise's backing track. The recording is a concert B♭ blues.
Return to JazzValve practice. Alternate one short phrase with one bar of silence. Finish with a slow ascent and descent. Your last repetition should sound easier, not louder.
