Trumpet
Brass instruments can play many interesting sounds beyond standard notation.
Above is an excerpt from the Fourth Movement of Solus by Stanley Friedman, it features a variety of different extended techniques. In this excerpt the second valve slide is removed creating a muted or “stopped” sound that can be quickly swapped to from the open sound. Additionally the third valve slide is contracted and extended to gliss smoothly between notes. The end of the excerpt has the player bend the pitch down an additional tone with their lips.
Flutter Tongue is notated with a a fast tremolo marking on the desired pitch/note duration and “flz.” or “Flutter”.
Half Valve Gliss
The Trumpet can make a convincing horse noise!
This is notated as a X notehead for the duration it should go for and the instruction “Horse Whinny”
The trumpet can also make percussive sounds.
Notated with X noteheads and “mouthpiece tap”, it can be pitched between written F#3 to C4.
All Brass instruments can also make atmospheric air sounds.
Notated with X noteheads and “blow air” as an instruction.
