Bright recently mirror polished old bowl with the straight inner sloping sides of a Trapezoid and a wide inner facing rim like a Thadobati. Clear extensive etching inside and out including a nicely done seven circle pattern in the flat bottom of the bowl. 528 Hz Solfeggio main tone with a very complex wave form in a simple soundscape. The strong Solfeggio tone bounces and wavers in a complex dance supported by essentially one short lived overtone. This is very much a pure 528 Solfeggio bowl. Sustain is OK, 30 seconds or so. It is very easy to play the main tone off the rim or even better the side of the bowl with simple wood. Even though the bowl is not large I would recommend a large ringing stick. Nice pure overtone with the specialized purple amaranth wand. Great looking bowl with a rare intensely focused 528 Hz tone. With overtones at F#6, . Solfeggio – MI 528 Hz.
