really useful vid this one and definitely a great choice of tune, as its got the repeating melody notes which can tie you up if you're not careful. well done and thanks for sharing
I suggest starting with the metronome set at between 80 and 90 BPM, where the beat is a quarter note. Our rolls are 8th notes, so you will want to play two notes per click. Do this with an Alternating pattern, strings 3251 over and over and your Thumb will always land on the click. Once you gain confidence you can play to the click and keep it steady, you can try to increase your speed and try other roll patterns.
