I am passed grade 1 and I decided to step back from learning and do some playing, so I got a easy fake piano book , I spent hours getting one song off really well playing about with the left hand , . Anyway my question is will this help my progress or hold me back? I noticed when using the fake book I spent a lot of time looking down at the piano keys but I seem to remember the melody parts quit well from the book .
Yeah a fake book won't help your progress.
Yes - it really helps the ear - and really makes theory practical.
