Hi guys!
Hope you are doing fantastic :) I'll post an analysis of my arr. of Beethoven's 5th later - but for now here's a description of this tapping thing I do, which should massively help to strengthen your left hand. It's a cool little thing to do just to flex, but most importantly it's a fantastic exercise.
It's a very simple pattern but will yield great results when it comes to your left hand tendons ⚡️ Get it down and practice in front of a TV, or impress your crush with it.. I don't know..
