Yes one thing is very true of teaching - you deliver a lesson one day and you feel like you absolutely nailed that topic. Student leaps forward.To me it's the other way around. Putting attention on a specific part of the body (The Fingertips), rather than specifically outside the body (the keys). Reminds me of the 'Inner Game' series of books where Tennis Students are asked to notice how the Tennis Ball is spinning rather than thinking about how to play a specific shot.
Next student comes in, you do your thing, and the student looks very blankly at you.
I think everyone knows this. It happens often. The thing that intrigues me is that there have been quite a few examples on here that I find absolutely baffling.
I started learning when I was 7. I had a good 14 or 15 years of lessons from several teachers, some from the highest level. Classical players mainly, the jazz was always something I did aside. One teacher of mine, a soloist and educator used lots of analogy - but I’m left wondering how on earth this helps: “classical sound is blowing with warm air and jazz sound with cold”.
Getz sounds pretty warm and full to me, not thin.
