These are written pitches for B♭ trumpet. Written G blues sounds in concert F, not concert G.
G blues scale trumpet fingerings chart
I’m using the six-note minor blues scale: 1–♭3–4–♭5–5–♭7. In G, that gives you G–B♭–C–D♭–D–F, then G again.
This chart runs from second-line G to G just above the treble staff:
| Written note | Staff position | Valve fingering |
|---|---|---|
| G4 | Second line | Open |
| B♭4 | Third line | 1 |
| C5 | Third space | Open |
| D♭5 | Fourth line, lowered a half step | 1+2 |
| D5 | Fourth line | 1 |
| F5 | Fifth line | 1 |
| G5 | Space just above the staff | Open |
Open means no valves pressed. Valve 1 is closest to your mouthpiece; valve 3 is closest to the bell.
The octave matters. Low D below the staff normally takes 1+3. This D takes 1. This D♭ takes 1+2, not the 1+2+3 used below the staff.
If those registers still blur together, keep my practical trumpet fingering guide nearby.

Play it up and down
Up: G–B♭–C–D♭–D–F–G
Valves: open–1–open–1+2–1–1–open
Down: G–F–D–D♭–C–B♭–G
Valves: open–1–1–1+2–open–1–open
Set your metronome to 60 bpm. Play quarter notes. Hold the last G for four beats, breathe, then descend.
I give the descending pattern extra time. F5–D5 uses valve 1 for both notes. Your fingers can’t help you find that drop. Hear D before you leave F, and keep the air moving without pressing harder.
Next, isolate D–D♭–C: 1–1+2–open. Keep valve 1 down while adding valve 2. Then release both together for C. Uneven release can let another pitch poke through. It doesn’t need a solo.
Finish with C–B♭–G: open–1–open. Keep the valve stroke quick even at a slow tempo. Slow practice doesn’t mean slow fingers.
If upper G feels strained, use D–D♭–C–B♭–G first. That keeps the important descending change without demanding the full octave.

Return to the G blues scale practice screen, but start your horn work on D. Play the five-note descent three times, resting between attempts.
Make the blue note sound intentional
Read the note and rhythm transcript below. Staff notation requires JavaScript.
Notes, rhythm and playing instructions
- Bar 1: beat 1, D5 eighth note, fingering 1, sounds C5, light tongue; beat 1.5, D-flat5 eighth note, fingering 1+2, sounds C-flat5, light tongue; beat 2, C5 eighth note, fingering open, sounds B-flat4, light tongue; beat 2.5, B-flat4 eighth note, fingering 1, sounds A-flat4, light tongue; beat 3, G4 half note, fingering open, sounds F4, light tongue.
- Bar 2: beat 1, whole rest.
Descending blue-note connection and rest 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.
For g blues scale trumpet fingerings, D♭ is the note I check for both timing and valve coordination. It’s the flattened fifth. Let it connect notes rather than land there by accident.
Start with the descending version:
D–D♭–C–B♭ | G
Valves: 1–1+2–open–1 | open
Play the first four notes as eighth notes, then hold G for two beats. That fills one bar of 4/4. Rest for the next bar.
Tongue lightly once through. Then slur D–D♭–C, listening for clean edges between pitches. Don’t clip D♭ just to hide the change.
Now reverse the middle turn:
C–D♭–D–C | B♭–G
Valves: open–1+2–1–open | 1–open
Use four eighth notes followed by two quarter notes. Press valves 1 and 2 together for D♭, then release only valve 2 for D.

Turn the scale into a short solo
I’d rather hear a clear answer than another trip up the ladder. Try this descending call and lower-register response:
- Bar 1: G5 quarter note, F5 eighth note, D5 eighth note, D♭5 eighth note, C5 eighth note, quarter rest.
- Bar 2: B♭4 quarter note, C5 quarter note, G4 half note.
Keep the rest. Change the rhythm only after the valve changes stay clean.
Listen to Miles Davis on “Freddie Freeloader” for space and blues phrasing, not as a play-along in this key. For this exercise, choose a concert F blues backing track. Concert G requires written A blues instead.

Use the G blues scale practice screen as your note reference. Play the two-bar phrase, rest two bars, then answer with your own descending line.
A five-minute practice routine
- One minute: Check g blues scale trumpet fingerings against the chart, ascending slowly.
- One minute: Descend G–F–D, keeping valve 1 down between F and D.
- One minute: Loop D–D♭–C, then rest.
- Two minutes: Play the two-bar phrase and vary its rhythm.
I stop increasing the tempo when the D♭–C release gets untidy. A clean descent is the point today.
