One day I'll practice my picking and i won't be able to play at 120bpm ,but after a few minutes of practicing I'll go from 105bpm to 120 on the metronome.Is there a way to stop this so i don't have to keep starting on the same old slow speed every day ?
I have never seen these exercises fail to improve my students' picking speed. The exercises are based on scales, but you can adapt them to any passage that you wish to improve.
