DESCRIPTION:
Patricia Cardona performs Gustnado by Derek Charke (2008) at the UO Flute & Electronics Concert on May 2, 2010.

Gustnado is a colloquial expression for a short-lived , shallow, generally weak tornado found along a gust front. Gustnadoes are usually visualized by a rotating dust or debris cloud.

The soundtrack is made up mostly of transformed flute sounds, some of which emulate sudden swirling figures, others are a sudden explosion and some granularised:sounds that are stretched in time, or are granules, short and fast. And there are many other transformations, plus a few electronic sounds.
The solo flute interacts with these dounds.

The score includes the solo flute part and a representation of the soundtrack with timings and other important information.

The flute part includes extended techniques such as multiphonics, aeolian sounds, timbre trills, over blowing on harmonics, harsh Ch K, Ch k sounds, and of course, ordinary tone production.

The piece is loosely in variation form with a flurry of sound in the introduction, then a presentation of the main thematic material, which is further altered and developed. A quasi recapitulation of the opening ends the piece.
