Ruach is a Hebrew word that can be translated as "breath," "wind," or "spirit." It is a piece written for solo contrabass flute that explores the sonic capabilities of the instrument as follows: air sounds, lip pizzicato, tongue pizzicato, tremolo with harmonic overtones, sweeping glissando throughout the upper partials of the instrument, and rapid succession of spectral multiphonics from low fundamentals.

Ruach was commissioned by Kelley Barnett and premiered by her on May 16, 2023, at Mise-en Place in Greenpoint, Brooklyn, NY, USA.

The piece is dedicated to Kelley Barnett.
