I am looking to improve my speed and accuracy, so I learned some excercies from John Petrucci's Rock Discipline video. I am not looking to be able to play at 200 bpm, I am not a fan of shredding. But I want to improve my speed. I have hardly every practiced with a metronome before and right now I can only do like 116 or maybe 120, and its getting sloppy. (I'm talking about playing 16th notes by the way.) Is it normal to start there? Or am I retarded?
Slow down until you can play perfectly at the tempo. Then, once you can play it perfectly, gradually speed things up day by day.
