I have never heard of a “prepared” piano before discussing it in this class. To be honest, seeing the piano all geared up like that makes my heart ache a little. John Cage invented this Frankenstein piano by placing different screws, nails, and other material among the strings in order to transform the traditional sound of a piano. The piano thus became a very percussive instrument through this process. Cage provides very detailed specifications for the preparation of this particular piano. The variety of materials used creates a wide range of different effects from the piano such as altered pitches and percussive, nonpitched sounds as well.
Cage composed a piece for his invention titled Sonatas and Interludes, which contains sixteen sonatas and interludes between sets of four sonatas. The piece featured in our Norton Scores is Sonata V. This sonata is in binary form and revolves around only five pitches from B to E-flat. It is a subtle reference, but the percussive elements, timbre and contour within this piece reflects influence from a Gamelan Ensemble. Cage’s style is truly unique and he has made a name for himself through his trademark of interpreting and transforming music to encompass the foundation of this art form: noise. This piece is both soothing and eerie at the same time. If one listens to it without knowledge of what instrument is being used, a piano with congested with screws and bolts will never be the first guess.
Even though I empathize with the piano and feel its uneasiness of having foreign objects within the midst of its well-structured stings and dampers, the “prepared” piano is an innovative and extremely original idea that I respect. I enjoy this piece very much and think it sounds mysterious and intriguing. I urge all of you to listen to the other sonatas and interludes of this work!
