This set includes two almost identical singing bowls. Two of these instruments individually are of high quality and could be easily used separately. However, as a set, they create magic patterns that are scientifically called "binaural beats". The measurable binaural beats effect is quite unique when it comes to two almost identical bowls.
The fundamental tones frequencies: B1.1: 208-211Hz G#3 Concert pitch (Sol#3)
The fundamental tones frequencies: B1.2: 210-213Hz G#3 +3Hz (Sol#3 +3Hz).
The difference (binaural beats) between lower frequencies 210 and 208 is 2Hz (Corresponds to Delta brainwave).
The difference between higher frequencies 213 and 211 is 2Hz (Corresponds to Delta brainwave).
First overtone B1.1: 608-616 (D#5-6Hz)
First overtone B1.2: 620-626 (D#5+4Hz)
Binaural 12Hz and 10Hz
An excellent set for any kind of practice for both beginners and advanced level practitioners.
Both bowls are playing super smooth the fundamental or overtone depending on your technique of rubbing the bowl either with suede padded or wooden end of the playing stick.
Set includes two complementary singing bowl cushions and two singing bowl mallets R2 and S1.
The diameter of B1.1: 9" (23cm) The weight is 71.7oz (2016g)
The diameter of B1.2: 8 3/4" (22.5cm) The weight is 62.4oz (1769g).
