Performer's guide to Cage's Sonatas and Interludes

[neotonicizer]

I'm pretty sure there are some John Cage or prepared piano enthusiasts on this board that will appreciate my detailed guide on preparing the piano.  This is specifically designed for Sonatas and Interludes.

Did you know that John Cage made kits of preparations for the Sonatas and Interludes and sold them through a new music journal published by Henry Cowell? These kits contained 45 envelopes, one for each note of the preparations, that held the hardware he used for his preparations. Did you know that Cage created a document for performers in 1949, after the publication of the Sonatas and Interludes, that further detailed his preparation process and intentions?  With this information, I believe performers can arrive at a better-prepared piano.
