A Rainbow in Curved Air

Terry Riley's "A Rainbow in Curved Air" is a keyboard fantasy from 1969 — Riley alone, overdubbing electric organ, harpsichord, dumbec, and tambourine into a shimmering, continuous improvisation. The music moves in rolling arpeggios and melodic spirals, tonally centered but harmonically free, drawing from Indian classical music's emphasis on raga-like modal exploration within a sustained drone framework. Riley had studied with Pandit Pran Nath, and the influence is audible not in literal quotation but in the quality of attention — the willingness to inhabit a single melodic cell for extended duration, finding variation within repetition rather than through contrast. The production is warm and slightly psychedelic, characteristic of late 1960s analog recording, the keyboard sounds bleeding into each other with a natural richness. The cultural moment — San Francisco, psychedelic era, the meeting of Eastern philosophy and Western experimental music — saturates every note. Yet the music transcends its moment; listened to now, it sounds as fresh and strange as it must have in 1969, a sustained state of musical presence that invites the listener to abandon destination and simply inhabit the sound.
