12 years and you dont know a single scale?
Lets assume you said please..
If you are gonna take it "serious" search around on pebbers page, all the scales are there..
I suggest you start by learning the major scale, but there is actually no pre given order, follow your ears.
Ill quote Satriani:
Once you learn all the things there are to learn about the theory of music, you realize that everything’s equal: Nothing is more important than the next thing. No chords are more important than each other and all scales are equal. Because it’s how you accomplish telling the story and how you move people. So if you’ve done it with a three-note scale or a 12-note scale, what’s the difference? From a musician’s point of view it’s almost like a carpenter—are different screwdrivers better than others? Not really if we’re talking about different shapes; it’s all about the appropriate tool.
And ill answer for Pebber.
Make an effort, watch the videos and browse the website, it is all there.
Learn them all!
