Prepared Piano       

              A Ready Piano May Be A Piano That Has Had Its Sound Altered By Putting Objects (Preparations) Between Or On The Strings Or On The Hammers Or Dampers.

             The Idea Of Fixing Associate In Nursing Instrument's Quality Through The Utilization Of External Objects Has Been Applied To Instruments Aside From The Piano; See, For Instance, Ready Stringed Instrument.

             Cage’s Early Compositions Were Written Within The 12-Tone Technique Of His Teacher Schoenberg, However By 1939 He Had Begun To Experiment With Progressively Unorthodox Instruments Like The “Prepared Piano” (A Piano Changed by Objects Placed Between Its Strings So As To Provide Music And Transcendental Sound Effects). Cage Additionally experimented With Tape Recorders, Record Players.
