Play along with the backing track. As an example use your phone to film yourself and send it over. I’ll watch it and will give you some feedback and tips. I prefer to receive an average take instead of the best take of your life.
I’ll be checking out the following:
– muting technique
– transitions
– timing
– posture
– fretting hand posture
– finger placement
– picking hand positioning
– picking movement
I’l score you 1-5 on every element named above.
If you find it really hard to play along with the backing track and it just doesn’t work out for whatever reason. Mention it in the recording like: I try to play along, but I just don’t get it. Do an attempt and send it over. I’ll check where it might go wrong and help you to work this thing out.
