Watch the Moore Me online guitar lesson by Corey Congilio from 50 Progressive Blues Licks You MUST Know
I mentioned earlier that Gary Moore was a big influence on me. Here's a lick I came up with that shows a little bit of his influence on me.
We're in C major here but playing the C minor pentatonic of course. Take this lick as an example of how to create a theme or melody. Notice how I start simply then get more intense in just 2 bars.
