Klavierstück IV is a solo piano piece composed by Karlheinz Stockhausen in 1962. It premiered on October 13, 1963, in Donaueschingen, Germany, performed by David Tudor. The piece is divided into three movements, with a total duration of approximately 12 minutes. The first movement of Klavierstück IV is characterized by its use of silence and sparse, isolated notes. The pianist is instructed to play with a "very light touch," creating a delicate and ethereal sound. The movement is structured around a series of short phrases, each separated by a pause. The phrases become increasingly complex as the movement progresses, with the pianist required to play faster and with more precision. The second movement of Klavierstück IV is more rhythmic and energetic than the first. The pianist is instructed to play with a "strong, sharp attack," creating a percussive sound. The movement is characterized by its use of repeated patterns and ostinatos, which build in intensity as the movement progresses. The pianist is also required to play with a wide range of dynamics, from very soft to very loud. The third and final movement of Klavierstück IV is the most complex and challenging of the three. The pianist is instructed to play with a "very fast, light touch," creating a virtuosic and frenetic sound. The movement is structured around a series of overlapping patterns and rhythms, which create a sense of constant motion and flux. The pianist is required to play with great speed and precision, navigating complex passages and sudden shifts in dynamics. Overall, Klavierstück IV is a challenging and innovative work that showcases Stockhausen's unique approach to composition. The piece is characterized by its use of silence, repetition, and complex rhythms, as well as its emphasis on the physicality of the piano and the pianist's performance.
