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.

Great Experimental App

Just found this app, much respect for John Cage and I really appreciate getting to work with his prepared piano! Would be really great for Midi control like the others said (core and/or virtual.) The Audiobus sdk is out now, I think its implementation with this app would be stellar. The only other suggestion I have would be an option to arrange the notes in order, this would be great to hear other tunes in the John Cage way! Oh and possibly a way to export the recordings with audiocopy or e-mail (Audiobus would solve this.) Thank you for bringing this to my iPad.

Nice Tribute to John Cage

Very enjoyable to play with and you don't have to stick foreign objects inside your piano! I like how you can upload a recording that you create onto the John Cage website to share with others. The ability to hook up a MIDI Keyboard controller to play the prepared piano sounds would be a very nice enhancement to this app.

Unfulfilled potential

John Cage's prepared piano sounds are inspirational, but this app offers no way to use them with other iPad music apps.

If the developers added midi and inter app audio support, my rating would be much higher. More in-app text about Cage and his method would be a great addition, too.

There is so much this app could offer users to do and learn. As it stands, John Cage Prepared Piano is neither useful for composition or recording nor is it especially educational.
