I look at music as a language and the notes as its alphabet and/or vocabulary. Scales are a way to organize this information so musicians can easily catalog and index the notes for their harmonic choices. In chord scale theory its a match game meaning that the notes that you choose to play are going to come from the scale that go with the chord that you are playing over. With that way of thinking about it, it soon becomes obvious that you need to know where all of the notes of a given scale are on the fingerboard and not just a couple scale pattern shapes. The following video is an online Skype bass guitar lesson on how to think about scales as you practice them. I hope you will consider some live online Skype bass lessons for yourself, they really work great and I can help you get better. Thanks for your time and interest.
