Solfeggio by Sonalkiss is the only app available on the AppStore that allows for realtime, multi-channel control of multiple solfeggio tones. The solfeggio tones originally identified by Pythagoras hold unique properties that affect all aspects of nature as well as man-made materials. The ability to control the amplitude of 9 simultaneous solfeggio tones allows for virtually unlimited possibilities for unique cymatic experiments as well as healing and holistic therapies.
