Takumi Ikeda (b.1975) is an autodidactic computer musician and composer. He performs live performances and composes contemporary classical music with his own programs. He has published his own composition aid program, LotusRoot, on GitHub. Many performers have performed his works; recently, he has been working on piano and soundtrack, baritone and computer, trombone with a 9-axis sensor module, mixed chorus, video scores for mobile devices, and scores for improvisers or a dancer. In his series of works for improvisers, which he calls “Musical procedure,” he experiments with a wide variety of notation methods, including video scores, to balance the players’ creativity with the identity of each work and to enable collaboration that does not depend on skill differences between players.

Recently, Ikeda has been questioning the normal way of music, and his production activities are based on the concept of “music for people who do not understand music” as the backbone of his work. His own suspicion of auditory processing disorder has made him aware of the diversity of senses and perceptions. Because of this, he selects materials based on the criteria that he can explain the rules for constructing music as concisely as possible. Ikeda is also oriented toward neuroatypical music, questioning the old view of music tied to collective human activity due to the rapid changes in world affairs in the 2020s. He sometimes composes using mathematics, such as the rotation of three-dimensional figures or graph theory, but he also combines extremely simplified materials like descending chromatic scale. Underlying these measures are ideas such as “considering the human voice as a percussion instrument” and “assuming that octaves do not exist,” for example, which can ultimately be reduced to the concept of “misuse of music.
