F4 Trombone Position
How to play F4 on the trombone: 1st position. — on the 6th 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 is all the way in, resting gently against the stops. The staff is in bass clef, the trombone's home clef, and in bass clef the trombone sounds exactly as written.

The F4 position, step by step
- Move the slide out to 1st position — the slide is all the way in, resting gently against the stops.
- First position is the home position: every harmonic of the open tube is available here, and your lips and air choose which one sounds.
- 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: 1st position.
Alternate position for F4
4th position.
Yamaha’s official chart badges this alternate. It rides the flattened seventh partial, so it is played short — pulled in from the ordinary 4th-position landmark. Other charts give 6th position (on the B♭4 harmonic) as F4’s alternate; that version is steadier for held notes, this one handier in a quick slur.
About F4 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.
F4’s badged alternate, 4th position, is played on the seventh partial — the flattened A♭ harmonic — so it is used short, pulled in noticeably from the ordinary 4th position landmark. Yamaha’s chart badges this version; other charts give 6th position (on the B♭4 harmonic) as the alternate instead. Both are documented: the 6th-position version is the steadier one for a held note, the 4th-position version the handier one in a quick slur.
F4 is note 20 of the 32 in the full trombone slide position chart, sitting between E4 below it and G♭4 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 F4
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.
Questions about F4
What position is F4 on trombone?
1st position. F4 is played on the 6th partial (harmonic) of the trombone's tube in the middle register. The full step-by-step is on this page, and you can hear the note with the Fingering Finder.
Does F4 sound as written on trombone?
Yes. In bass clef the trombone is a non-transposing instrument, so written F4 sounds as concert F4 — the same pitch a piano plays. Only brass-band treble-clef parts transpose.
Is there an alternate position for F4?
Yes — 4th position. Yamaha’s official chart badges this alternate. It rides the flattened seventh partial, so it is played short — pulled in from the ordinary 4th-position landmark. Other charts give 6th position (on the B♭4 harmonic) as F4’s alternate; that version is steadier for held notes, this one handier in a quick slur.
