I have uploaded a new recording to my website sound clips page. It is a short excerpt (only 1:46) from my piece “Of Sound and Mystery” in which I experiment with sounds containing 2, 3, or more overtones. Perhaps some of you are working on similar techniques. (select #6 on the player). New recordings will be added soon, including my work with lyrics and overtones. http://www.stuarthinds.com/sound-clips/
