This is two small Thadobati cups set. TcD#72 is an old bowl (18th century) and her twin flame TcD#78 is a little younger (20th century). Two of these instruments individually are of high quality and could be easily used separately. However, as a set, they create magic patterns that scientifically called "binaural beats". The measurable binaural beats effect is present in this set on four levels, but it's far more than the frequency analyzer is refusing to pick!
The fundamental tones frequencies: TcD#72: 612hz-623hz (D#5+1hz)
The fundamental tones frequencies: TcD#78: 620hz-632hz (D#5-2hz)
Difference (binaural beats) between lower frequencies 612 and 620 is 8hz
Difference between higher frequencies 623 and 632 is 9hz
Between the next binaural beat pair of tones, there is the first overtone of TcD#78 which is 1236-1240hz and second overtone of these bowl creates the binaural effect with the first overtone of TcD#72 1733-1738hz and 1768-1774hz
Binaural 35hz and 36hz
Excellent set for any kind of practice for both beginners and advanced level practitioners.
Both bowls are playing super smooth by rubbing the rim with the wooden end of the playing stick.
Set includes two complementary singing bowl cushions and two singing bowl mallets R2.
