You can study those choices without adding range or learning a longer solo. This lesson uses one sustained pitch and an original four-bar melody to compare vibrato placement. It is a phrasing lesson, not a prescription for changing your embouchure.
Hear three separate choices
For this lesson, listen for three features:
- Onset: how long the note stays straight before vibrato begins.
- Rate: how quickly the motion repeats.
- Width: how far the pitch moves during that motion.
Rate and width are different. A narrow vibrato can be quick; a wide one can be slow. You do not have to change both when you want a different effect.
Brass vibrato can involve changes in intensity as well as pitch. Dennis Herrick's research on hand and jaw vibrato, held by the University of North Texas, examines those as separate measurable features. In your own recording, notice whether you hear pitch movement, repeated changes in loudness, or both. A louder ending by itself is not evidence that you added vibrato.

Know the technique names without choosing one blindly
Two common terms are jaw vibrato and hand vibrato. Brian Weidner's brass-technique chapter describes jaw vibrato through small jaw and tongue adjustments, and hand vibrato through gentle hand movement that changes the instrument's contact with the embouchure.
These names describe ways of producing the effect, not different musical styles that everyone must use. For the exercises below, keep the comfortable method you already know. If you have not learned a controlled vibrato, ask a trumpet teacher to demonstrate it on your setup rather than inventing a large horn-shaking motion from a written description.
You can still complete the listening and straight-tone comparisons now. The University of Texas Ray Sasaki demonstration collection includes a trumpet-vibrato segment for close observation. Watching a player is a useful supplement to an individual lesson, not proof that copying every visible movement will produce the same sound.
Make a listening map before playing
Choose a short passage from a jazz recording you already enjoy. Find two sustained trumpet notes, preferably within the same phrase. You do not need to transcribe the pitches yet.
Listen three times, with a different question each time:
- Does the motion begin with the attack or after a straight opening?
- Does its speed or width change before the release?
- Is the next held note treated the same way?
Write a compact description such as “first ending: straight, then narrow motion; second ending: straight throughout.” If you cannot hear a clear pattern, choose a more exposed passage rather than assigning a technique you cannot identify.
Keep the observation tied to that performance. One note is not enough to conclude that a player always uses one kind of vibrato, and the sound alone may not tell you which physical method produced it. The jazz-listening guide offers a broader framework; this time, stay with the ending of just one phrase.
Exercise 1: Move the onset, keep the note
All pitches here are written for standard B-flat trumpet. Written G4 is second-line G and sounds concert F4. C4 means middle C, below the treble staff. B-flat trumpet's major-second transposition is documented in UTEP's instrument reference.
Set 4/4 at quarter note = 72. Play written G4 as a whole note, followed by a whole bar of rest. Use a comfortable dynamic and record the following versions separately:
- A: Keep the note straight for all four beats.
- B: Keep beats 1–2 straight; introduce a small, controlled vibrato at beat 3.
- C: Keep beats 1–3 straight; introduce the same kind of vibrato at beat 4.
The vibrato onset changes, but the note's attack and release do not. Each version ends at the start of the rest bar. Do not re-tongue when the vibrato begins or add a new accent to announce it.
Use the metronome to place the onset and release. For this comparison, it is not a demand to fit a fixed number of vibrato cycles into each beat. Keep the rate and width as similar as you comfortably can between B and C so that placement is the main variable.
Listen back without playing. Which version makes the ending sound most deliberate? If B and C sound indistinguishable, make the straight portion easier to hear rather than immediately widening the effect. If controlled vibrato is not available yet, keep A as your playing task and mark the intended onsets for a lesson with your teacher.

Exercise 2: Choose which phrase receives it
Play this original melody in 4/4 at the same tempo. Learn the notes without vibrato first:
- Bar 1: G4 quarter note on beat 1; A4 quarter on beat 2; B-flat4 half note on beats 3–4.
- Bar 2: A4 half note on beats 1–2; half rest on beats 3–4.
- Bar 3: F4 quarter note on beat 1; G4 quarter on beat 2; A4 half note on beats 3–4.
- Bar 4: F4 half note on beats 1–2; half rest on beats 3–4.
Rest for another two bars after the melody. The written range is F4–B-flat4, with no octave leap. Play unaccompanied; this is an original phrasing study, not the melody or chord chart of a jazz standard.

Notes, rhythm and playing instructions
- Bar 1: beat 1, G4 quarter note, sounds F4; beat 2, A4 quarter note, sounds G4; beat 3, B-flat4 half note, sounds A-flat4.
- Bar 2: beat 1, A4 half note, sounds G4; beat 3, half rest.
- Bar 3: beat 1, F4 quarter note, sounds E-flat4; beat 2, G4 quarter note, sounds F4; beat 3, A4 half note, sounds G4.
- Bar 4: beat 1, F4 half note, sounds E-flat4; beat 3, half rest.
- Bar 5: beat 1, whole rest.
- Bar 6: beat 1, whole rest.
Written for B-flat trumpet, unaccompanied, quarter note = 72. Bars 1–4 are the source melody; bars 5–6 are the explicitly requested recovery rests. Learn it straight first. On a separate take, add vibrato only on beat 2 of A4 in bar 2, or only on beat 2 of F4 in bar 4. Do not reattack or change note lengths. No fixed vibrato rate or width is notated.
Make three takes:
- Keep every note straight.
- Add a small vibrato only on beat 2 of the A4 in bar 2. Leave bar 4 straight.
- Leave bar 2 straight. Add the same effect only on beat 2 of the F4 in bar 4.
In takes 2 and 3, the affected note begins straight on beat 1 and releases at beat 3. You are moving emphasis between the two phrase endings without adding notes or changing their lengths.
Compare the complete melody, not only the decorated note. Does the earlier ending draw attention away from the final one? Does leaving the first phrase plain make the second sound more conclusive? There is no required winner. Choose a version you can explain in musical terms and repeat intentionally.
Change rate or width on a separate pass
Once placement is dependable, return to version B of the single-note exercise. Compare two comfortable rates while keeping the onset at beat 3 and the pitch movement similarly narrow. Rest and listen between attempts.
On another day, compare a narrower and slightly wider effect while keeping the onset and rate similar. There is no need to find an extreme in either direction. If the pitch begins to wander or the effect takes over the phrase, return to the smaller version.
Separating the decisions helps you describe what you want. “Later onset, same width” is a clearer instruction than “make it more expressive.” In a horn section, agree on the intended effect with the leader or follow the arrangement rather than independently decorating every long note.
Keep a straight ending available
Finish by playing your chosen melody version, resting, then playing it completely straight again. Both should feel like intentional performances. Vibrato is one available color; dynamics, articulation, space and the release still contribute to the phrase.
For a longer slow-tempo application, continue with the jazz-ballad trumpet study. Choose one held note to experiment with instead of adding the same effect everywhere. The free Blue Lines workbook is also available with email signup for additional short practice material.
