Traditional / experimental practice

Beyond Perception · The Ghost Melody

The ten overtones of a low tone (110 Hz) all play together. When a narrow filter brings them forward one after another, a melody is heard inside the sound, yet no tone is added or removed: only the balance of the overtones changes. Overtone singers draw out melodies in a similar way. A listening practice with no claim of any effect.
