Pair of antique Koprepatti binaural singing bowls (17”–18”), accompanied by:

A large wood and leather mallet

A cotton striking mallet

These binaural bowl pairs are available in different frequency ranges, allowing you to choose the state you wish to explore:

Alpha waves (8–13 Hz): Medium-frequency brainwaves associated with relaxed, calm states during wakefulness, such as light activity, walking, or mental ease.

Theta waves (3.5–7.5 Hz): Low-frequency brainwaves linked to deep relaxation, meditation, and the transition between wakefulness and sleep, including REM states.

Delta waves (1–3 Hz): Low-frequency brainwaves associated with deep sleep and profoundly restorative states.

Each pair works binaurally, creating subtle frequency differences that support deep listening, relaxation, and internal focus.
