Watch the Simplicious online guitar lesson by Neil Zaza from 50 Melodic Rock Licks You MUST Know
Playing a simple melody that works over a progression is great. Getting a melody to repeat over and over on top of the chord progression underneath is gold, baby! I call this style of melodic playing a circular melodic theme because it is basically a loop of a melody repeated over and over for maximum impact. Notice that we are addressing the key of the song (E major in this case), but also acknowledging some of the more interesting chord tones of the progression (C in this example). If constructed correctly the listener will not only hear the actually melody that you are playing, but be drawn along to the chords underneath.
