Watch the Minor and Major Scales online guitar lesson by Angus Clark from Hard Rock Survival Guide: Lead
Now that I've enticed you into this course with some very approachable and very rock n roll stuff, I'm going to take advantage of your enthusiasm by dropping mad science on you with a few lessons about playing scales. You'll be all the better for it. As with concept one, this is also an opportunity to work on your picking and metronome synchronization. These are skills that develop over time by practicing consistently on a regular basis. They also require maintenance, even veteran performers and players run their scales to stay "in shape" on the instrument. So get used to it, and while it's ok to do it in front of the tv sometimes, definitely listen to what you're playing more of the time. Play them as slowly as you need to to play them absolutely perfectly before starting to speed them up.
Once you start speeding up the metronome, if you really want to get the most out of it, pay attention to things like your breathing and if you have tension in your hands, shoulders or jaw, etc. I find that remembering to breath normally and remembering to smile help relax tension and improves my performance. And that's a hot tip.
If any of the terminology confuses you, just take a minute and wrap your head around it: There are seven notes in a diatonic scale. I refer to them by the number of the scale degree, I use Root and "1" interchangeably. Jazzbos like to refer to the 2, 4, and 6 as the 9, 11, and 13, cause they like having their own exclusionary language. I use that terminology sometimes, but I don't consider myself a jazzbo, so there. Anyway, truth be told I really see the neck as notes, like A, C#, Eb, etc. The numbers game is effective in teaching because I am encouraging you to practice these exercises in all twelve keys, so do that. What I do not see are fret numbers. I can't read tab and that's never lost me a gig. I can read standard notation and that has gotten me gigs, so you can glean from that whatever you want. Moving on.
