The John Cage Trust
has released a cool prepared piano app
for iPhone and iPad, called CagePreparedPiano. It contains samples of a piano prepared using the same exact materials that John Cage used to create his Sonatas & Interludes for Prepared Piano,
one of his most famous works. It's been recorded several times, including recently by Adam Tendler,
who offers a full performance for free download.
I spent part of John Cage's 100th Birthday today writing and recording two new little prepared piano pieces in homage, using the prepared piano app.
The first Cagean "Sonata" is a single movement in three parts, recorded playing my iPhone.
