Watch the Polka Dots and Moonbeams online guitar lesson by Mimi Fox from Jazz Performance

I harmonize the melody here in both thirds and seconds, the latter of which is unusual and I feel gives the tune a bit more of an edge than you might expect. With solo guitarist's nice sometimes to harmonize with just one note rather than an entire chord because it creates more space. By playing intervals it is more full than just the one note, and yet still leaves you some air a good thing to explore in your own solo playing. I recommend my TrueFire course "Flying Solo" for absorbing these ideas better.
