Trombone: Difference between revisions

Line 2:

Trombones are usually written in concert pitch, with a couple of exceptions:

- Contrabass, G bass, and Bb bass are all written in bass clef, untransposed.

* Contrabass, G bass, and Bb bass are all written in bass clef, untransposed.

- Tenor trombones can be written in bass clef or tenor clef untransposed, and occasionally (in British brass bands) in treble clef transposed up a major ninth.

* Tenor trombones can be written in bass clef or tenor clef untransposed, and occasionally (in British brass bands) in treble clef transposed up a major ninth.

- Alto trombones are written in alto clef, untransposed.

* Alto trombones are written in alto clef, untransposed.

- Soprano trombones are usually written in treble clef, untransposed or (less commonly) up a whole step, the same as Bb trumpets.

* Soprano trombones are usually written in treble clef, untransposed or (less commonly) up a whole step, the same as Bb trumpets.

Like most brass instruments, trombones sound on an approximated [[harmonic series]], and their ability to gliss encompasses tritones descending downward from each partial. For example, tenor trombones, pitched in Bb have partials of Bb-Bb-F-Bb-D-F-Ab-Bb . . . as per a 1:2:3:4:5:6:7:8 . . . harmonic series, and the glisses can descend a tritone down from each of those partials. This system gives trombones unparalled pitch sensitivity compared to other brass instruments, and in expert hands, trombones are extremely versatile, capable of being extremely lyrical, blending, or raucus as the orchestration requires.
