Considered as a healing practice—or a “tuning of mind and body”—Oliveros’s “Sonic Meditations” are, to an extent, unique in the history of musical experimentalism. In these works, experiments were not conducted on the music; the music was an experiment on the self. Anyone searching today for the complete box set of “Sonic Meditations” won’t find it, because, as the composer wrote, “music is a welcome by-product” of this composition. The experiments remain in each listener. Oliveros’s aims were clear: these works were intended to be transformational, even therapeutic, enacting lasting changes on the body and mind.
