Watch the Melodic Patterns online guitar lesson by Jeff McErlain from Blues Guitar Survival Guide - Lead
Humans like patterns in everything we do, our brains seek them out. As a musician patterns are essential to what we do. We can call them melodic sequences which is a fancier name. Patterns also give us time to think about where we want to go next musically as well as giving some order to the music. I have provided some basic pentatonic melodic sequences to get you started and you can start to create your own. There are many books out there dedicated to patterns but the grandaddy of them all is the Thesaurus of Scales and Melodic Patterns by Nicolas Slonimsky. I'm not suggesting to run out and buy this very daunting book, patterns can be very simple to very complex.
