Everybody here wss a blockhead once upon a time. Things are only what they are at the time they are those things. The biggest hurdle is getting the bottle to ask these questions in open forum. You just passed that test, my friend. Now, I suggest you stop doing yourself (and your musical future) a disservice and get youself a pure music theory book. Not some half-arsed 'for dummies' or 'for bassists' nonsense, but the real thing, published by a proper academic music school. Put down your bass and start reading. As you've already seen, this forum has some pretty knowledgeable, experienced and qualified people who have all the time in the world for those willing to ask genuine questions that need factual answers rather than opinion. We may not always see eye to eye on many things, but when it comes to the facts, we are a goldmine.
