This lession looks very easy to play, but is not so easy. If you want more to do with your left hand for 2 finger style playing is this right lession!

1 - i (index finger) 2 - m (middle finger)

start to play with low speed (like 50bmp) or less or more, but don't forget to play correct in time! Then speed up "metronome"

First you play: i m i m i m (121212) every single note Second you play: m i m i m i (212121) every single note

Good luck!
