In front of a crowd, yes. It would be an embarrassment. But in my humble opinion if you want
to play fast you have to get in the mindset of fast. Even if sloppy at first. Again, totally agree
with the metronome practice. Vital part. But what is cool is I've watched sloppy fast players turn
into smooth fast players with practice. It just kind of gets your fingers and mind in the "speed" of
things. Eventually the slop turns into smooth. I spend a part of each practice paying as fast as
I can move my hands--usually on chromatic or pentatonic scale in doubles, triplets, and quadruplets.
