The tenor trombone reads at concert pitch in bass clef, with tenor clef for high passages. Its slide gives it a true glissando and also makes some fast passages awkward.
Trombone registers
| Register | Range | How it sounds |
|---|---|---|
| Pedal | B♭1 and below | Pedal notes below the normal range. Rough and loud, used for effect. |
| Low | E2 to B♭2 | Firm and dark, blending with tuba and bass trombone. |
| Middle | B♭2 to F4 | The trombone's main voice, from a soft chorale to a full-throated blast. |
| High | F4 to B♭4 and up | Bright and heroic. Some sources stop the full range at D5. |
Writing for the trombone
- The slide has seven positions. A glissando only works across notes the slide can reach without changing partial.
- Legato needs a soft tongue between notes, so very fast slurred lines are harder than on a valved instrument.
- Trombone chords in close position are one of the warmest sounds in the orchestra.
The trombone in sample libraries
Trombone legato patches often smooth over the slide, so they sound easier than real slurs. Check the legato of any library against a fast passage before relying on it.
The full range is every note a professional can produce. The practical range is narrower on purpose, leaving out the notes only strong players produce reliably. The figures here are cross-checked between orchestration references, and where they disagree the practical range takes the more conservative one.
