Arjuna, member of Overtone Music Network, provides on his website www.harmonicfuzion.com his concept of harmonic singing. If you would like to know and listen more about this concept, please check out the Transcription Excerpts from Arjuna's Harmonic Fuzion CD - to be fair I recommend to purchase this CD via PayPal. Arjuna's lessons are highly recommended.
