A Minor Triad Inversions: Trumpet Fingering Exercises

These a minor triad inversions trumpet fingering exercises turn three written notes—A, C, and E—into practical jazz phrases.

Start with A3–C4–E4, using valves 1–2, open, 1–2. Play each note for one beat at 60 bpm, then rest for one beat. Repeat four times without rushing the open C.

All notes here are written pitches for B-flat trumpet. Middle C is C4. Written A minor sounds as concert G minor, so choose concert G minor accompaniment if your backing track uses concert-pitch labels.

A minor notes and valve fingerings

A minor contains a root, minor third, and perfect fifth: A–C–E. The C natural gives the chord its minor quality. Substituting C-sharp would make it A major.

Use these standard fingerings throughout the drills:

| Written note | Valves | Where it sits | | --- | --- | --- | | A3 | 1–2 | Below the staff | | C4 | Open | Middle C, below the staff | | E4 | 1–2 | First line of the staff | | A4 | 1–2 | Second space | | C5 | Open | Third space |

Notice that A3, E4, and A4 share the same valve combination. Your fingers cannot select the right pitch by themselves. Hear the note first, then coordinate air and embouchure without forcing the jump.

On the horn, A3–C4–E4 alternates pressed valves, open valves, and pressed valves again. Keep your fingertips close to the buttons because lifting them high makes clean changes harder.

An inversion changes which chord tone sits lowest. The notes still belong to A minor, but the spacing and melodic direction feel different.

1. Root position: A–C–E

Play A3–C4–E4, then rest.

• Valves: 1–2 → open → 1–2.
• Rhythm: three quarter notes and a quarter rest.
• Repeat: four times at 60 bpm.

First, tongue each note lightly. Then slur the three notes. Listen for an even tone across both changes, rather than a bump on E4.

2. First inversion: C–E–A

Play C4–E4–A4, then rest.

• Valves: open → 1–2 → 1–2.
• Rhythm: three quarter notes and a quarter rest.
• Repeat: four times at the same tempo.

The E4–A4 leap is a perfect fourth with no valve movement. It can expose an uncertain pitch target. Sing those two notes first, then play them softly enough to avoid muscling the upper A.

If the leap cracks, isolate E4–A4. Tongue both notes before trying the slur again.

3. Second inversion: E–A–C

Play E4–A4–C5, then rest.

• Valves: 1–2 → 1–2 → open.
• Rhythm: three quarter notes and a quarter rest.
• Repeat: four times.

Release both valves together when moving to C5. However, do not let the easier open fingering tempt you to accent that note automatically.

Keep C5 comfortable. If the top note feels strained, return to the first two shapes and rest before continuing.

Connect the shapes without stopping

Next, make each inversion into a six-note loop:

1. A3–C4–E4–E4–C4–A3. 2. C4–E4–A4–A4–E4–C4. 3. E4–A4–C5–C5–A4–E4.

Play six eighth notes, followed by a quarter rest in 4/4. Begin with even eighth notes so timing problems remain obvious. Then try a relaxed swing feel without clipping every second note.

During these a minor triad inversions trumpet fingering exercises, separate finger problems from pitch problems. A blurred C4–E4 usually calls for cleaner valve coordination. A cracked E4–A4 needs a clearer pitch target, because the valves stay down.

Record one pass. Listen for equal note lengths, clean starts, and a final note that stays supported rather than fading accidentally.

For a useful comparison, play the C major triad inversion drills. C major shares C and E with A minor, but uses G instead of A.

Turn the drill into a jazz phrase

Over a written Am7 chord, A, C, and E are the root, third, and fifth. You can make a convincing short phrase without adding the seventh immediately.

Try C4–E4–A4, followed by a beat of silence. Then answer with C5–A4–E4. The silence gives each shape a clear boundary, so it sounds less like continuous exercise material.

For a ii–V connection, play written A4–C5–E4 over Am7, then move E4 down to D4, valves 1–3, when D7 arrives. That final note targets the new chord's root.

Listen to Miles Davis on “Autumn Leaves” from Cannonball Adderley's Somethin' Else. Notice the space around his phrases. These drills are original exercises, not a transcription of that recording.
