Two color Thadobati black and brass. The artwork is extensive and sharp. Despite the obvious wear my guess is this is a 20th century bowl. Bright and lively soundscape with strong overtones being the strongest part. The fundamental middle C note has a slow soft pulse. Longevity is good, the overtone outlasts the fundamental. The quiet bass becomes front and center with the leather side of a ringing stick, wood sings out the overtone with excellent longevity. Not a wand bowl. With overtones at F#5, F#6. Solfeggio – SOL 741 Hz Overtone.
