Have you ever noticed the intriguing resemblance between Toru Takemitsu's "Rain Spell" and Pierre Boulez's "Derive"? It's quite astonishing to think that Boulez composed his work merely a year after Takemitsu's piece premiered in Japan. Could it be possible that Boulez had heard Takemitsu's work before creating "Derive"? We may never have concrete answers. Yet, it is not uncommon for two individuals to independently explore similar ideas without knowledge of each other's endeavors.
The most striking connection lies in the instrumentation of Takemitsu's "Rain Spell": Flute, Clarinet, Harp, Piano, and Vibraphone. Boulez's "Derive" follows a similar path with flute, clarinet in A, vibraphone, piano, violin, and cello. The notable difference lies in the addition of violin and cello, perhaps to achieve a balanced string timbre. While the harp serves as an intermediary instrument in Takemitsu's work, the piano assumes that role in Boulez's composition. It is worth mentioning that the tuning of the harp evokes a touch of "far-eastern mysticism," resembling the sounds of traditional Japanese instruments like the Koto or its Chinese cousin, the Guzheng. Hence, it is not solely the instrumentation that draws parallels.Both composers employ rising scales and prolonged notes, particularly trills, in a similar manner, creating a shared sonic aesthetic. This convergence of instrumentation and technique contributes to a semblance in their musical language. At times, one could easily mistake a passage from one piece for the other. Nevertheless, Boulez's composition exhibits a more pronounced abstract structure, embarking on a precise and deliberate journey. In contrast, Takemitsu's "Rain Spell" takes the listener on a dreamy and meandering expedition, captivated by the present moment.
Upon discovering that Takemitsu's composition predates Boulez's "Derive" by approximately a year, I was taken aback. The publishing dates confirm this fact, although we cannot determine when each composer began working on their respective pieces. If one of them indeed had the opportunity to hear the other's creation beforehand, it is plausible to assume some form of influence. The truth remains elusive, leaving us to ponder and for you to draw our own conclusions.
I urge you to immerse yourself in both compositions, explore their intricate tapestries, and unravel the mysteries that lie within.
