There has been a lot of debate on the nature and existence of 22 Shrutis in India for a long time. Dr.Oke has provided a detail mathematical foundation with a precise formula as a basis to generate the Indian 22 Shrutis. Thereafter, using the formula, he has synthesized the sounds of the 22 Shrutis accurately on the Synthesizer and has modified a traditional harmonium with European 12-Tone Equitempered tuning to a patented 22-Shruti-Harmonium.

The instrument is extremely melodic and creates consonances with the purity of the Tanpura e.g., Shadja-Gandhar-Pancham, Madhyam-Dhaivat-Shadja, Pancham-Nishad-Rishabha, Madhyam-Komal Nishad-Rishabha, Komal Gandhar-Pancham-Komal Nishad, etc, never heard so accurately before. What is surprising is that when several/all the notes in the same Raga are played together, they still do not create any dissonance. The 22-Shruti-Harmonium therefore seems to provide the answers to the challenges found by the traditional harmonium while playing Raga-Sangeet.

The 22-Shruti-Metallophone created by him is a handy instrument providing accurate and standardized sounds of 22 Shrutis and can be used both by students and the experts. "
