K I'm reading this book, trying to understand what the Major Scale and Pentatonic Scale is, and i have no idea what the hell it's talkin' about. It's rubbish. Any know of any good books or online tuts? =) Thanks.
There's tons of them. Google it.

There's scales lessons on this forum, click LESSONS at the top.

I very much doubt the book is rubbish, you'll find pretty much the same explanations in whichever or whatever book/lesson you read.

It's hard to get your head round at first but once you do you'll realise how easy it is. Look forward to your "Aaaahaaaaa" moment.
Haha, yeah i was thinkin' that, but when i read it and look at the diagrams it's all just "guhh what....margarine?"
