This lesson develops one original idea across eight bars. Everything stays between written C4 and G4 on B-flat trumpet, so you can concentrate on entrances, note lengths and the relationship between phrases.
A motif is a small, recognizable musical idea. Its identity might come from its rhythm, its pitch shape or both. For this exercise, the identifying feature is an upward sequence of three notes: C4, E4, G4.
Repetition gives the listener another chance to recognize that shape. A change in rhythm or placement then gives the familiar material a different direction.
In Berklee's “Focus on the Framework”, saxophonist Bob Reynolds recommends limiting an improvised chorus to the rhythm or shape of its opening phrase. Here, we'll make that constraint smaller and easier to hear.

Use 4/4 at a comfortable starting tempo, such as 60–72 BPM, with one metronome click per quarter-note beat. Play at an easy volume after your normal warm-up.
All exercise notes and chord symbols below are written for B-flat trumpet. Written C4 is middle C, on the ledger line below the treble staff; G4 is on the second line. Written C4–E4–G4 sounds concert B-flat3–D4–F4.
You can play unaccompanied or over a single sustained chord:
The three exercise notes are the root, third and fifth of that chord. You don't need to add the seventh to the melody. Keeping the harmony still lets you hear what each rhythmic change does.
Count one bar aloud: “1, 2, 3, 4.” Play:
Release G4 on beat 4, and keep counting through the silence. Use a light, consistent tongue on each entrance. Repeat this bar until the rest lasts a full beat and the next C4 arrives without rushing.
If you're still getting comfortable with short phrases, the beginner call-and-response lesson offers a useful starting point. Here, keep returning to this same motif rather than choosing a new riff.

Repeat exactly. Let the second statement match the first. Resist adding notes just because you've already played the idea once.
Move the entrance. Rest on beat 1, then play C4, E4 and G4 on beats 2, 3 and 4. The notes and their lengths stay the same; the whole idea begins one beat later.
Compress the rhythm. Play C4 and E4 as eighth notes on beat 1 and the “and” of 1, followed by a quarter-note G4 on beat 2. Rest on beats 3 and 4. The rising shape now occupies two beats.
Lengthen the ending. Play C4 and E4 as quarters on beats 1 and 2, then hold G4 as a half note across beats 3 and 4.
Ed Saindon's Berklee lesson on rhythmic phrasing encourages practicing different starting positions while retaining awareness of beat 1. Keep the metronome steady as your entrance moves around it.
Read the note and rhythm transcript below. Staff notation requires JavaScript.
Make the original eight-bar repetition, delayed entries, compression and lengthened ending visible. Source first pass uses even eighths. Optional later swing in bars 5 and 6 is a feel instruction, not a 2:1 duration rewrite. Optional accompaniment only: written C7 sounds concert Bb7; Sustained throughout all eight bars. 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.
Play this sequence without stopping. Every bar contains four beats. Unless specified otherwise, each named note or rest lasts one quarter-note beat.
Use even eighth notes for the first pass. Once the counting is secure, try your familiar swing feel consistently in bars 5 and 6.
Breathe during the written rests, especially at the end of bar 6. Stop afterward and rest before another attempt. If eighth-note placement needs attention, practice it separately with the swing eighth-note guide, then return to the same eight-bar sequence.
Record one pass, then listen without playing. Can you recognize the opening idea in the later bars? Do the delayed entrances stay in time? Does the longer final G sound intentional?
Next, improvise eight bars using only C4, E4 and G4. Choose the order of the rhythmic variations yourself. Leave at least one exact repetition so the original idea remains clear. If everything changes at once, return to the written sequence.
When you take this approach into a tune, keep its chord changes and form intact. The 12-bar blues form lesson can help with that next step; this eight-bar study uses one chord and isn't a blues chorus.
