I played through most of the free lessons before deciding to join, and I can say that joining is COMPLETELY worth it. They tell you how many lessons are on here before you join (I don't remember the number, but I remember that it was very large) but you can't quite comprehend the sheer scope of this site until you get to play with it for a while. It's so easy to get completely sidetracked with random lesson plans (I spent a few hours learning about MIDI sequencing and stuff... I'll probably never use it in my life!) but it's just so much fun. Anyway, this is the type of website that causes subscribers to starve to death because they're too busy practicing and exploring to eat. Best website ever. I love it so much I think I'll marry it.
