Daphne oram / ORMICS

An Individual Note of Music, Sound and Electronics (1972), Daphne Oram does use the word “celetal”—but not as a typo. She intentionally coins “celetal”, playing on “cele”, which is “elec” reversed, to evoke a kind of counterpoint between the celestial (spiritual, creative) and the electric (technical, electronic) en.wikipedia.org+15paperzz.com+15daphneoram.org+15.

From Resonance- The Journal of Sound & Culture (vol 2, issue 4 Winter 2021)
In her book An Individual Note (1972), Daphne Oram developed multiple extended analogies between humans and electronic sound technologies. Oram used these to suggest how “music and information theory, allied to technology” might be applied to mental health; and to support her design for a machine that would preserve human qualities through its interactivity and musical results. This music machine, Oram wrote, “is based mainly on controlled feedback and the computing of resultants.…It is a control system which could be applied to many fields, as well as music.”
