What´s the speed for this in bpm. Vai´s is damn fast so and I guess that´s around 140-145 bpm, but he dosen´t hold the same tempo throughout wich maby is easyer. I strictly hold the same tempo when playn´ with metronome but when playn´ it frelly, I guess I speed up some easy parts and slow down hard. That´s why I find metronome important.
