This book came in the post today (About Time). I'm about to start this 52 week course and just wondering if there are any pointers I need before I start. Unfortunately I don't have access to a teacher at the moment so I'm going solo on this one. I'm pretty sure this book contains no tunes, should I still play tunes whilst I work my way through or play only what is in the book? Also, looking at the first lesson, the exercises get pretty damn high. Do I need to be able to play the highest note in this lesson in order to move on to lesson 2? Thanks!
