About

Classical listening, shaped around you.

Two inputs,
one session

PureTone asks two questions — your mood, and how much time you have — and curates one session to fit. Answer those two, and the session is ready: sequenced, timed, and presented in 432 Hz. Those two choices shape the session.

Mood + Time
→ Session
Mood Time Session

Two choices. One considered session.

Human-performed,
software-curated

PureTone sequences real classical recordings using its own curation system, scoring and ordering works by mood and duration. The software decides the order; the performers made the music.

PureTone’s
sonic identity

Sessions are presented at 432 Hz — PureTone’s chosen tuning, and part of what makes it sound like PureTone. It runs through every mood and every session, a consistent thread across the catalog rather than a one-off setting.
