Impetuoso (2002) by Sunji Hong
for flute, clarinet, violin, cello, and piano
US premiere

The title suggests impetuous, violent and dashing gestures that underline the direction of the music. Particular attention was given to the timbre of instruments in their different registers.

The piece is in two sections. The first five bars introduce the prominent sound materials of the piece: aeolian sounds, fairly slow, irregular oscillations and sul ponticello with extreme bow pressure. The sound materials are transformed in various ways throughout the piece by juxtaposing different techniques or moving from one sound-type to another.
