What Cosmazul sounds like
Soft, drifting layers
Keyboards, synths, and guitar, played slowly and layered until the edges blur. Nothing sharp, nothing sudden.
Sleep frequencies
Some tracks are tuned to gentle delta and 528 Hz tones — the kind of low, steady sound that helps a busy mind settle.
Long enough to drift
Tracks stretch out and stay level, so there's no big finish to pull you back awake.
Cosmazul is Jeremy Siegel, a California artist who makes music from his home studio in Los Angeles. The name is a mix of "cosmos" and "azul" — the Spanish word for blue.
"Helping people find peace or fall asleep through my music is one of the most rewarding feelings in the world," he says. That's the whole idea behind every track: keyboards, synths, and guitars, played soft and slow, until the sound feels like something you can rest inside.
