Theory?

What is the theory thing everyone is talking about here and there???

It's the theory of how music works. It's mainly made up after people came with good-sounding stuff

Learning theory helps tremendously, even though it can seem like a chore. But when you start to get it and apply it, it's a great feeling
There are loads of websites and books covering theory, so get learnin'!

can you point me into a direction? ie website?

http://www.studybass.com/ is a good place to start
