Simple large Thadobati with a broad flat bottom and hammermarks. This thin bowl is bright outside and has creamy original patina inside. Rich and resonant with an extremely well balanced soundscape. There is quite a bit of depth to this premium harmony bowl. The bass thumps while the very solid overtone sings. Very good sustain. While leather will play a bit of the bass it does not grip well for overtones. The massive and tiny yew wands are the way to spin the rim with wood, they minimize the rim contact notice. Great rim sustain with whatever wood you spin it with. With overtones at B4, A#5, F#6.
