Learn a short written-C exercise, check your valve combinations, and transfer the pattern from screen practice to your B-flat trumpet.
I listen closely to D4–E4 on my B-flat trumpet: valve 1 stays down, so the clean change depends on exchanging valves 3 and 2 together. I keep the E4–G4 leap gentle rather than trying to force the open G.
Use virtual trumpet valves to rehearse C–D–E–G before picking up your B-flat trumpet. Start slowly: C is open, D uses 1–3, E uses 1–2, and G is open.
That gives you something useful to play immediately. However, the goal is not simply remembering four combinations. You want each change to arrive on the beat without an extra note slipping between pitches.
This five-minute routine separates the fingering problem from the blowing problem. Then you bring them together on the horn.
All notes here are written trumpet pitches, not concert pitches. On a B-flat trumpet, written C sounds concert B-flat. Keep that distinction clear if you check pitches against a piano.
Use this comfortable starting register:
| Written note | Position | Valves | | --- | --- | --- | | C4 | Ledger line below the staff | Open | | D4 | Space below the staff | 1–3 | | E4 | Bottom staff line | 1–2 | | G4 | Second staff line | Open |
Valve 1 is nearest your mouthpiece. Your right index finger operates valve 1, your middle finger operates valve 2, and your ring finger operates valve 3.
For more combinations, keep the trumpet valve chart nearby. However, stay with these four notes until the sequence feels predictable.
Play or rehearse C4–D4–E4–G4, giving each note one beat. Then reverse it: G4–E4–D4–C4. Use a metronome at 60 beats per minute, or slower if you hesitate.

Screen practice is useful for connecting note names with valve combinations. It also lets you work through a sequence when you cannot make noise.
However, selecting the right valves does not guarantee the right pitch on a trumpet. C4 and G4 are both open. Your air and embouchure must select different notes from the instrument’s harmonic series.
Likewise, tapping a screen does not reproduce valve travel or spring resistance. Treat the screen as a fingering rehearsal, not a replacement for playing.
If your fingers lose their place, say the combinations aloud: open, one-three, one-two, open. Then repeat without speaking. This makes hesitation easier to notice before breath and articulation enter the picture.
Minute 1: identify. Look at each note and name its fingering. Work through C4, D4, E4, and G4 in order. Then try E4, C4, G4, and D4.
Minute 2: keep time. Rehearse C4–D4–E4–G4 as quarter notes at 60 beats per minute. Count aloud. If you miss a change, slow down rather than rushing to catch up.
Minute 3: isolate D–E. Alternate D4 and E4. Valve 1 stays down while valve 3 releases and valve 2 goes down. On the horn, aim for both moving fingers to complete the exchange together.
Minute 4: make a phrase. Use this original two-bar exercise in 4/4:
Minute 5: transfer. Pick up your trumpet and play the same phrase softly. Take a comfortable breath before each attempt. Rest between repetitions so tired lips do not obscure the finger work.

The D4–E4 exchange is the most revealing movement here. If the second and third fingers move unevenly, you may hear a brief unwanted pitch between the notes.
First, slur D4–E4 slowly. Listen for one direct change rather than a little wobble. Then tongue the same pair lightly without using the tongue to hide uneven fingers.
The E4–G4 leap presents a different challenge. Both valves release, but the lips and air must also find G4. If the note cracks, return to E4, hear G4 internally, and try again without forcing volume.
Keep your fingertips near the valve buttons. Large finger lifts add unnecessary movement, especially when the ring finger must return for D4.
Listen to Miles Davis playing “So What” on Kind of Blue. Notice his use of space and contrasting phrase lengths. This exercise is not a transcription; borrow the listening habit, not an invented connection to his solo.
Play the two-bar phrase, then leave two bars silent. Next, repeat it with a lighter first C and a settled final C. Keep the written rhythm unchanged while exploring emphasis.
Finish your virtual trumpet valves session in JazzValve’s practice screen. Rehearse C4–D4–E4–G4, then E4–D4–C4, holding the final C for two beats. Take that exact phrase back to your trumpet and listen for a clean D–E change.
