Sonatas and Interludes (1948) by John Cage for prepared piano: a tribute to Merce Cunningham through the music of John Cage.
The music for prepared piano was born from Cage's pragmatic need to accompany the dance. Le Sonatas and Interludes (1948) represent one of the tops of this period: listening and performance go beyond the concert dimension, the music represents a continuing evolution performance where every sound sourprise "like walking collecting shells on the beach" (Cage).
Like a natural organism, with an autonomous and mysterious life, Cage's compositions are a continuous experiment and research of compositional methods to make a work unique and unrepeatable, to "hide the beauty", to "free the life of sound" from subjective tastes, to encourage the listening attitude where the modification of oneself comes before the confirmation of one's expectations.
