Celebrate the music of John Cage by playing the John Cage Piano app on your iPad. One of the many ingenious innovations of American composer/writer/artist John Cage was his creation of the "prepared piano", in which he placed objects beneath and between the strings of a grand piano to create an entirely new instrument.

The sounds of John Cage's prepared piano are now available for you to play on your iPad with this innovative app. Play meticulously sampled sounds of a piano prepared with the actual materials used by John Cage in the preparations for his Sonatas and Interludes (1946-48) as sampled under the supervision of the John Cage Trust.
