Geometric pitch structure and form in déserts by Edgard Varèse

Meer over het boek

Focusing on the geometric constructs in Edgard Varèse's Déserts, the analysis delves into the pitch structure, revealing distinct sound planes formed by adjacent pitches. It emphasizes Varèse's vision of "music as spatial," showcasing how tension and release manifest through the interaction of trichords. The work's alternating acoustic and electronically organized sections create a continuous seven-part form, with the collision and repulsion of pitch planes indicating clear formal structures. This exploration highlights the innovative integration of instrumental and electronic elements in the composition.
