Swing, western swing, and even blues and country players play this one! This lick uses the basic notes in the chord, and especially brings out the major 6th of the scale. In the key of C, it would be an A (just count up the notes in the scale: 1, 2, 3, 4, 5, 6 - C, D, E, F, G, A). In the key of G, it would be an E. The 6th is a signature sound in early jazz and in fact almost all American roots music. Later when we get more into a 1950's jazz sound, we'll start using the major 7th more and more.
A fun way to work out using this (and any of the licks on this course) is to play it as many different ways as possible. Once you can play it comfortably along with the track, try it out on different string sets. For example, start the lick on the A string or even the E string. You'll have to adjust your fingerings, but that will be easier now that you know the lick and your ear can guide you.
If you play it down low on your treble pickup and double up on every note, you'll have that classic boogie-woogie bass line! Then, try mixing and mish-mashing all of the notes! Play the lick backwards, slide into notes, try starting it on different beats...very much like using a new word in a sentence. Once you've created variations on the lick, and used it in many different "musical sentences", each lick will become part of your own personal vocabulary.
