 Despite the fame "Sonatas and Interludes" earned him, and the connections he cultivated with American and European composers and musicians, Cage was quite poor.Although he still had an apartment, at 326 Monroe Street (which he occupied since around 1946) his financial situation in 1951 worsened so much that, while working on "Music of Changes", he prepared a set of instructions for Tudor as to how to complete the piece in the event of his death.Nevertheless, Cage managed to survive and maintained an active artistic life, giving lectures, performances, etc.
