I experience it much as a vocal student does a difficult piece of music- one practices, imperfectly, until one "gets it". Then you recreate the "feel" of hitting the notes, and connecting the phrases fluidly. Eventually, the mind doesn't control things so much as the "feeling" becomes natural. This is the place where the music happens.
it's interesting changing, I am a musician and not only has life come full-circle with me returning to my original career I gave up in my late teens because I didn't think I was 'good enough', but it affects me differently to be the musician now. I used to think each time was about getting better and better and reaching for an unatainable perfection...and that it was down to practice and that 'getting it' was mechanical.
Having mainly seniors and alzheimer patients to sing for gave me a space to try singing with the spirit, for I have so much love and admiration for these people, most of whom I am watching get sick and die whilst continuing to sing themselves...
I once said to one of my directors 'I wonder when I'll really be able to sing out' and it's taken years even from then, but hasnt been about training or even practising so much as connecting my spiritual self to the voice and just letting myself be there in that moment and share it perfectly with the people around.
It doesn't matter of my voice breaks or I miss a note, for every now and then an angel sound comes out of me and I know now- that is perfection, noticing those wonderful sublime moments when they arrive, not trying to make them happen on demand on automatic pilot!
I used to think there was a formula for life and everyone else got it, at least more than I did, like with mathematics or chemistry. And I got the same mental block as with those things- like it was mystery and not for me, I'm no rocket scientist or concert pianist so I should step back and leave it to people who can do it. A whole symphony shut down in me for a long long time. Now I realise the music was going on in and around me the whole time, I was just numb to it, just like when I see quadratic equations and hear the laughter and strictness of my various math teachers echo in my head 'you can't do it'.
Can! And will!!!
