Re: Back to basics?
In my experience, it is a "going back to" basics that is an important stage, not necessarily building a "foundation". I am sure that most of us start practicing and it is all new and exciting and then it becomes a bit boring, so we look for more advanced stuff. Then there is a point where we realize we don't find what we are looking for in the advanced stuff, so many quit. Those who get really good, though, find a new quality in the old, the basics.
We then regret all the time "wasted" going after the advanced stuff and try to warn newer people, "Don't worry about advanced techniques, the key is the basics." I don't know about you guys, but I never really listened when being being told this.
I have read that the great Jazz pianist, Bill Evans, used to sit at the piano for an hour, just playing one note, over and over. However, that was after a lifetime of Jazz and he was a genius.
