Rare extra thick old Thadobati with a very broad inner facing rim that has deeply etched rim lines and faint worn interior circles. A fine example of the oldest singing bowl art. Pure and powerful super high frequency bowl, almost 1000 Hz with excellent sustain for the size and style. Premium harmony. The penetrating purity of this bowl’s sound is exceptional. As usual with these super thick super high frequency bowls rim play is negligible. I did see a Solfeggio 963 Hz reading pop up with simple wood. This is a mallet bowl, with exceptional sound. With overtone at E7.
