Dear Enrique, Thank you for your wonderfully detailed information on Tuvan throat singing. I went to the website you recommended and for some reason, I couldn't get my Real Player to play the spectrograph illustrations. It kept on buffering and then cutting out and rebuffering. I did find one all-too-brief example on another website. That made me happy to hear the wondrous sound again. When I was a child I used to try to sing chords--at night--under the covers so nobody could hear me. Too bad I lived in Long Island, not Tuva!
