I know there is more to scales than just an easy, non-musical finger exercises, but every book I've read so far gives the pattern for a scale and basically says "scales are good, learn scales". So, I learn the patterns to a few popular scales and that's it. I find them to sound pretty ugly, and most to be pretty technically easy to do (and I'm a beginner...). So why? Can anyone give me a practical reason as to the significance of these patterns? How do I apply them musically? I've looked everywhere on the net and in books, but can't seem to get an answer to that seemingly very basic question. HELP!
