Some say that you must perfectly play something before increasing your metronome or you will always play sloppy. Others say you must leave your comfort zone or you will never get faster.
I have been using the first method and I don't seem to be gettin any faster. What are your opinions on what works?
Also I heard another key to speed is relaxation. I can't seem to keep my jaw from locking if I play fast trills. What are ways you have learned to ease muscle tension.
Thanks in advance!
