Traditional / experimental practice

Solfeggio Path · Layers of Timbre

Two (1278 Hz) and three times (1917 Hz) the frequency are added one by one above a 639 Hz pure tone, then withdrawn. Whole multiples make no beats; the timbre of a single tone thickens. The overall loudness is kept steady, over the Deep Field's dark sound field. Sound design and listening practice; 1278 and 1917 Hz are not on the Solfeggio list.

Compare with another sound

Hear both at the same loudness; drag the slider to the middle and they blend.

These two sounds can't share one recipe (different tuning or effects): listen to the samples one after the other.

S · Soundscape, no claim

This session isn't linked to any claim of effect.

A session's level is the weakest of its linked claims; it is never raised by a strong but unrelated claim.
