174 Hz Pure Tone | 3 Hours for Deep Work and Focus

174 Hz, three hours, no voice. The tone sits at the root of the harmony, so nothing beats against it. The bed underneath is built on 87.000 Hz, which is 174 Hz brought down by octaves: the same note, lower. The slow movements that make the sound breathe have periods that never line up, so no stretch of the three hours repeats another. The lowest of the nine, felt as much as heard. Audio with a slow animated scene on screen. For work, study, reading, or quiet company. 174 Hz is one of the nine Solfeggio tones. These pieces use the scale as a tuning system. Original sound, digitally generated for this video (not a field recording). No attribution required. Produced for Inner Flows.
