G3 Trombone Position
How to play G3 on the trombone: 4th position. — on the 4th partial, in bass clef, sounding exactly as written.
The diagram shows the trombone from the side with the slide pointing down: the dark bar is the slide brace, and it stops at the numbered marker for this note's position — the slide brace sits just past the edge of the bell. The staff is in bass clef, the trombone's home clef, and in bass clef the trombone sounds exactly as written.

The G3 position, step by step
- Move the slide out to 4th position — the slide brace sits just past the edge of the bell.
- Move from the elbow with a relaxed wrist, and place the slide by ear as much as by landmark — positions are places you hear, not marks on the tube.
- Check the pitch against the harmonic: if the note will not speak cleanly, the slide is usually close and the lips are aiming at the wrong partial — re-centre the buzz before moving the slide further.
In short: 4th position.
About G3 on the trombone
The middle register is the trombone’s home territory — the 4th, 5th and 6th partials, where school band music mostly lives. This is where the classic alternate positions appear (F3 in 6th belongs to the register below, but B♭3 in 5th and D4 in 4th are here), and where the flat 5th partial has to be managed: its notes sit about 14 cents low and want the slide a touch in from the landmark.
G3 is note 10 of the 32 in the full trombone slide position chart, sitting between G♭3 below it and A♭3 above it. Like every position on this site, it was checked against Yamaha’s official chart and the NoteAtlas slide position chart before publishing.
Practising G3
Practise this note against a tuner, and if it belongs to the 5th partial (B3 to D4), expect to sit a little inside the textbook landmark. Then play it in a phrase — position is a habit of the arm, not a measurement.
