Sounds like your teacher has you playing the blues.

I think this has been discussed at length and is probably in a newbie section somewhere, and there is likely a chorus in the wings waiting the sing the 'Get Thee to a Teacher' bit, but I'm feeling benevolent and too lazy to go find the posts and soo will give you a bit.

First off, you're going to have to know the cycle of 4ths and the scales that go with the chords. Before I go too far and sound like gibberish, answer me those two questions.

I take most of the above back. Read: http://www.talkbass.com/html/modules.php?name=News&file=article&sid=53 and let me know if you're still confused. If you look in the Newbie section you'll find a ton of information to answer your question.
