Notes

From the 端山貢明アーカイブ (Hayama Kōmei Archive), item 126293 in the 音楽(楽譜) (scores) category, registered 2023-12-04: https://d-commons.net/hayama/?c=&p=126293. Published by the 端山貢明アーカイブプロジェクト (Hayama Kōmei Archive Project), directed by 前川道博 (Michihiro Maekawa) of Nagano University, on the D-Commons platform, and licensed CC BY (表示). The source documents come from the 端山文庫, the papers kept in Hayama's laboratory at Tohoku University of Art and Design, digitised by the project with the agreement of his family; his autograph scores were given to the University History Archives of the Tokyo University of the Arts in 2026. Source: Autograph manuscript score, 端山貢明 Collection; 20 pages. An untitled autograph score of twenty pages which the archive catalogues as number 51 and judges, from its materials and hand, to be an electronic-music score belonging with 《曲舞》 (Kusemai). Kusemai, named for the medieval Japanese song-and-dance form, dates from 1978 and is identified by the archive's own overview sheet as Hayama's last composition; it was given in a revised premiere by the Tadao Sawai ensemble in June 1980. The pages are time-ruled rather than barred, in the graphic notation he used for works involving tape and percussion. The score is held unidentified, and the archive is explicit that the attribution to Kusemai is an inference rather than a reading of any title on the manuscript. Noted: Untitled and undated; the connection to Kusemai is the archive's inference.
