For trumpet practice, the useful sound is a moving line around a major-sixth chord. Start by hearing those chord tones, then use the extra note to connect them. The exercises below are original studies, not excerpts from a recorded solo.
Major bebop and dominant bebop are different
The word “bebop” names more than one scale. Compare these written-C collections:
| Scale | Notes before the octave repeats | Added passing note |
|---|---|---|
| C major bebop | C, D, E, F, G, A-flat, A, B | A-flat, between G and A |
| C dominant bebop | C, D, E, F, G, A, B-flat, B | B, between B-flat and C |
Major bebop keeps the major scale's B natural. Dominant bebop starts from Mixolydian, which contains B-flat, and adds B natural. They are not interchangeable names for the same fingering pattern. Use the dominant bebop lesson when your task is outlining C7.
A-flat can also be spelled G-sharp, particularly in an ascending line. Here, the flat-sixth spelling makes the added scale degree easy to recognize. New York Jazz Academy's Bebop Line Building lesson distinguishes the major and dominant versions and illustrates their beat placement.

Hear C6 before playing all eight notes
All notes and main chord symbols in this lesson are written for B-flat trumpet. Written C6 sounds concert B-flat6. Use that concert chord for a piano accompaniment or backing vamp. B-flat trumpet sounds a major second below written pitch, as shown in UTEP's transposition reference.
C4 means middle C, one ledger line below the treble staff. Begin in 4/4 at quarter note = 60, using an easy volume.
Play these four quarter notes over written C6:
C5–A4–G4–E4
Then rest for one complete bar. Those notes are the root, sixth, fifth and third of C6. Sing the same line before repeating it on the trumpet. The descending C–A leap matters: A is the sixth, not the seventh.
Compare the chord spellings:
- C6: C–E–G–A.
- Cmaj7: C–E–G–B.
A major-bebop line can be used over major-seventh harmony, but its familiar on-beat pattern outlines 1, 3, 5 and 6, not all four notes of a major-seventh chord. Starting with a C6 vamp lets you hear that distinction without another chord tone competing for your attention.
Fill the spaces between the anchors
Keep the four notes from the previous exercise on beats 1, 2, 3 and 4. Insert one eighth note after each:
| Count | Written note | Job in this exercise |
|---|---|---|
| 1 | C5 | Root |
| and of 1 | B4 | Connects C to A |
| 2 | A4 | Sixth |
| and of 2 | A-flat4 | Chromatic passing note |
| 3 | G4 | Fifth |
| and of 3 | F4 | Connects G to E |
| 4 | E4 | Third |
| and of 4 | D4 | Leads toward the next C |
| Next bar, 1 | C4 | Root arrival |
Use even eighth notes in the first bar. In the second bar, hold C4 for two beats, then rest for two beats. The two bars contain exactly eight quarter-note beats.
Listen closely to A4–A-flat4–G4. Each move is a half step, and A-flat passes between two C6 chord tones. Do not turn it into a long resting note by accident. It adds a particular tension against the major harmony.
If the descending octave is too much to coordinate at first, play only A4–A-flat4–G4–F4 as four eighth notes on beats 1–2, followed by a half rest on beats 3–4. Then return to the complete line.
The full descent's alignment depends on its starting note, starting beat and continuous eighth notes. Beginning on a different subdivision or inserting a rest changes the result. Count the actual phrase rather than assuming the scale guarantees chord tones on every beat.

Let the major line arrive after a dominant chord
Use this four-bar progression, one chord per bar:
- Written trumpet harmony: G7 | C6 | C6 | C6.
- Concert accompaniment: F7 | B-flat6 | B-flat6 | B-flat6.
Play the following original phrase. Quarter notes each last one beat; a half note lasts two.
- G7: G4 quarter, B4 quarter, D5 quarter, B4 quarter.
- C6: C5–B4–A4–A-flat4–G4–F4–E4–D4, all eighth notes.
- C6: C4 quarter, E4 quarter, G4 quarter, A4 quarter.
- C6: G4 half note, E4 quarter, quarter rest.

Notes, rhythm and playing instructions
- Bar 1: beat 1, chord G7, G4 quarter note, sounds F4; beat 2, B4 quarter note, sounds A4; beat 3, D5 quarter note, sounds C5; beat 4, B4 quarter note, sounds A4.
- Bar 2: beat 1, chord C6, C5 eighth note, sounds B-flat4; beat 1.5, B4 eighth note, sounds A4; beat 2, A4 eighth note, sounds G4; beat 2.5, A-flat4 eighth note, sounds G-flat4; beat 3, G4 eighth note, sounds F4; beat 3.5, F4 eighth note, sounds E-flat4; beat 4, E4 eighth note, sounds D4; beat 4.5, D4 eighth note, sounds C4.
- Bar 3: beat 1, chord C6, C4 quarter note, sounds B-flat3; beat 2, E4 quarter note, sounds D4; beat 3, G4 quarter note, sounds F4; beat 4, A4 quarter note, sounds G4.
- Bar 4: beat 1, chord C6, G4 half note, sounds F4; beat 3, E4 quarter note, sounds D4; beat 4, quarter rest.
Written for B-flat trumpet. Quarter note = 60; use even eighths first. Written harmony: G7 | C6 | C6 | C6. Concert accompaniment: F7 | B-flat6 | B-flat6 | B-flat6. Preserve the source A-flat4 spelling in bar 2.
The range is written C4 to D5. If D5 is not comfortable, replace it with G4 in bar 1; the following B4–C5 resolution stays intact.
Bar 1 uses G7 chord tones. The major-bebop descent starts only when C6 arrives. This separates the dominant's approach from the tonic's color instead of running one C scale indiscriminately across both chords.
On a second pass, replace bar 3 with A4 half note, G4 quarter, quarter rest. Keep the other bars unchanged. You now pause after the descending line and give the sixth more space. Record both versions and listen for a clear arrival on C in bar 2.
Move the idea without moving every exercise
For written F major bebop, the notes are F–G–A–B-flat–C–D-flat–D–E–F. The extra note is D-flat, between the fifth C and sixth D. Written F6 sounds concert E-flat6.
Try one bar over that chord: D5–D-flat5–C5–B-flat4 as eighth notes on beats 1–2, then A4 as a half note on beats 3–4. Rest for the next bar. This moves the small sixth-to-fifth connection into a new key without requiring a long scale drill.
Once the notes and counts are secure, apply a relaxed swing feel. Keep the numbered beats steady, using the swing-eighth lesson if the subdivision needs separate attention.
Finish by naming the added note, singing the C6 anchors, and playing one four-bar phrase. For more short practice ideas, Blue Lines is a free jazz trumpet workbook available with email signup.
