Mutations: Etudes for Extended Piano Techniques

“Mutations” is a set of etudes utilizing common extended techniques for piano: Sympathetic vibrations; Touch harmonics; Finger techniques; and Prepared piano. The structure (as well as influence on specific etudes) is directly from György Ligeti's, “Musica Ricercata” in which each piece is confined to a pitch class, and the subsequent piece adds an additional unique note to a new pitch class.
