Short flat bowl with a mandala formed of punch circles with a sharp central six pointed star. It appears to me that this old bowl was cleaned up and re-etched. You can see the former design of a punch circle mandala somewhat randomly arranged, mostly worn away. Certainly a bowl with a history . Resonant and complex soundscape, reminiscent of an old ship’s bell but with a lot more character. Premium harmony, where the tones evolve and eventually simplify through the good sustain, at 30 seconds you can still hear the fundamental note. The bowl features a 528 Hz Solfeggio overtone which is the strongest in the bowl. Great off the rim, overtone with leather, second overtone with a wand. Smooth to volume and excellent rim sustain. Excellent choice if you are looking to drone the main Solfeggio tone. With overtones at C5, A#5, F6, B6. Solfeggio – MI 528 Hz Overtone.
