As an adult beginner, I find myself mulling the hows and whys of my practicing much more than I ever did when I (briefly) studed piano as an 8 year old. As a youngster, I was expected to practice for a certain amount of time (enforced by my parents, usually) and the quality of my practice didn't even enter my mind.
Now that I am "beginning again" so to speak, my time is limited, I have goals and expectations and all that, and I want my practice time to count (pun only half intended). Unfortunately, being a "grownup" and self aware means that I often end up being hyper-critical and much more easily frustrated than I ever was at 8 (also, much easier to sound bad at the fiddle than the piano. grrr, intonation!). Recently I came across this very thought provoking, helpful website: http://musicalfossils.com/index.html that I think is just brilliant. Probably I'm not the only one in my situation, so I wanted to share.
The author is a piano teacher but his reflections on practicing in particular are absolutely spot-on relevant (at least for me) to learning and practicing the fiddle (or any instrument probably) as an adult. http://musicalfossils.com/prac.html Now I need to go practice.
A toast to musical fossils here and everywhere!
