"Your discussion of "Just Intonation" is very interesting."
Thanks - use the Mudcat search engine to dig around on those terms - you will unearth heaps of threads with much more detail...
"Robin, is there more you can say about "aural feedback control of the voice" or does it require being there and hearing it demonstrated?"
Ahhhmmm... to be succint is the problem...
It would seem to be difficult to demonstrate it to someone else, as the whole point of it is that it is internal to oneself ....
I have a friend who could not hold a tune. She was told from very young that she could not sing and so believed it! Her idiotic singing teacher had never showed her how to listen to her voice, so I showed her with a simple physical trick, and with a little practice, she was amazed that not only could she now hear how just out of tune she was when singing along to her favourite CD's, but with some practice, she was improving - although she was fighting nearly 20 years of self perputuating brain washing that she was "tone deaf"!
The simple physical trick is this:
Put the palm of one hand to touch one ear, perhpas bending it forward slightly.
Instead of your voice normally being heard internally through your skull, your brain can now detect through your ear a far greater percentage more of the reflected external sound.
You must have seen singers doing this - it is often used as a source of humour anyway...
This does really assist oneself in "aural feedback control of the voice", something which is happening subconcousily all the time anyway.
