Harmonic singing in an Anechoic Chamber

The University of Wollongong has installed an anechoic chamber in the Creative Arts building for various research. This was my third time in. Of Which i must thank Eva Cheng for making this possible. Yes you hear your ears and blood rather quickly. One becomes over aware of just yourself which is probably why they use it for torture. Actually the sensation reminded me of various experiments I did with Erv Wilson when his Scale-A-Tron organ was working. Because it manifest it pitches from a very high crystal driven pitch, if one picks the right key one can have chords in 'absolute' as opposed to just tunings. By absolute meaning not a beat in say 10,000 years. but i have digress, i guess to touch upon the similarity. During the second time end i tried doing some harmonic singing, not that i am a singer at all, but found afterwards, i felt quite altered on leaving. This time i went in with that purpose and had my pettersons tuner to give and allow me to see how steady my pitch was. Due to the quiet one can hear much higher harmonics in ones voice but as these get closer and closer, it gets harder to find the perfect resonant position to accent it. I found myself though for the first time moving much closer in between the harmonics and began to explore the space in between these strong points. Here were all types of subtle shifts of timbre that i hadn't been able to hear before. For today i picked Meta-Mavila to be the base pitches. In the 1/2 hour i recorded i sang only nine tones over a range of an octave and a third. i plan to put these together in the future. next i and planning to record on the subharmonic series to see how it all sounds when it is all put togethersince there will be one pitch all the harmonic series will have in common.
