Watch the Let's Get Funky In D! online guitar lesson by John Goldsby from Upright Bass Handbook
Let's play "Let's Get Funky in D" together at a slow tempo. We'll play each exercise twice. I'll call out the number of the example--1, 2, 3, 4, 5, 6--as we move through the chart. This etude uses the open D string, and the D on the G string. Play the D on the G string with your 4th finger. We can play all of the other notes in this etude from this hand position: D, C, A, and G.
Make sure that the D on the G string is in tune. You can check your intonation by using the open D string and playing the high D. Once that's in tune, you're in position to play the notes C, A, and G. You don't need to (and you shouldn't) move your left hand out of this position to play any of the notes.
