Thick Thadobati with clear interior etching. The bowl has a two texture exterior, smooth at the top with the hammermarks evident below. Single solfeggio 528 Hz frequency bowl that starts with a fluttering burst of sound. This bowl is very much focused on the fundamental. Longevity is only fair. Not much of a stick bowl, no play with leather and just some fundamental tone sound with wood. With overtone at F#6. Solfeggio – MI 528 Hz.
