i like to start a warm up with some mixolydian scales. its not the hardest of scale forms so its good for the beging guitarist who wants a good warm up exersize. go up and down the neck with these scale patterns, going down the pattern onece and then back up then slideing to the next pattern, starting slow but then building up in speed. this is a c mixolydian pattern. wholenote has all the patterns in its scale finder.
