Elevated in Sapporo, Hayasaka was a self-taught composer. He became fast close friends with Akira Ifukube, another autodidact, afterwards well-known for his music associated Toho’s film monsters. Jointly they arranged the Shin Ongaku Renmei (SONGS Group) in 1933. In 1935 Hayasaka constructed his initial orchestral piece, the award-winning Futatsu no sanka e no zensokyoku (Prelude to Two Hymns). His following orchestral piece, Old Dance, earned the Weingartner Award in 1938. In 1939, he shifted to Tokyo to be able to start his long profession being a film music composer. His initial rating was for Ribbon o musubu fujin (THE GIRL Ties a Ribbon) aimed by Satsuo Yamamoto in 1939. Hayasaka created music for over 90 movies during his profession, most of them observed and award earning classics. But he concurrently continuing his creation of concert music, creating the orchestral piece Saho no mai to uho no mai (Still left Dance and Best Dance, 1942), his well-known Four unaccompanied tunes to poems by Haruo for solo soprano (1944), and a Piano Concerto (1946). In 1948, he obtained Yoidore tenshi (Drunken Angel), his 1st film for movie director Akira Kurosawa. Advanced overdubs were needed when no tape recorders had been to be enjoyed. In one picture, 12 songs needed to overlap in exact synchronization using the imagery; this may be achieved just after many requires involving cued vinyl fabric records. The worn out technical movie director was discovered weeping inside a corridor throughout a break. From 1947 until 1953, Hayasaka was an associate from the Shin Sakkyokuha Kyokai and in 1950 founded the Association of Film Music. During this time period, he published the Capriccio for winds and piano (1949), a String Quartet (1950), as well as the Metamorphosis for orchestra (1953).

In the entire year 1954, for another Kurosawa traditional Shichinin no samurai (The Seven Samurai), Hayasaka conceived a funny theme obtained for bassoon, piccolo, and bongos expressing the apishness of acting professional Toshiro Mifune’s personality. This was achieved despite the fact that Hayasaka’s prolonged tuberculosis started to get worse as he worked well through over 300 orchestral cues inside a two-month period. Because of this work, he received a stand-alone credit around the display, something by no means previously accorded a composer inside a Japanese film. He also provided music for Mizoguchi’s Chikamatsu monogatari (The Crucified Enthusiasts) and Sansho dayu (Sansho the Bandit), and Toshio Sugie’s Mitsuyu-sen (The Dark Fury) in 1954. During 1955, he made up Yukara for orchestra, a collection predicated on an epic from the isle peoples known as the Ainu, as well as the film ratings for Mizoguchi’s twelfth hundred years warrior epic Shin heike monogatari (New Stories from the Taira Clan) and Kurosawa’s Ikimono no kiroku (I Reside in Dread). Hayasaka finally succumbed to tuberculosis soon after completing Kurosawa’s anti-atomic bomb film Record of a full time income Being.
