Playing on the A, D, and G Strings by Eric Starr and Nelson Starr
As just mentioned, Figures 4-4 through 4-12 give you a chance to practice playing on the A, D, and G strings. When plucking the strings, alternate as much as possible between your index and middle fingers. Some players even use their ring finger. When using a pick, make sure to use a downward (down pick) as well as upward (up pick) motion. This is accomplished by driving the pick through the string in an up or down alternating fashion.
Figures 4-4 through 4-9 concentrate on the A string:.

In Figures 4-10 through 4-12, you will need to modify your left-hand fingering on the G string. Here you'll use finger one on fret two (A), finger three on fret four (B), and finger four, the pinky finger, on fret five (C). Fingering is always subject to revision, personal comfort, and musical necessity, and it can actually be a creative endeavor. For example, some bassists prefer to use the fourth finger in place of the third finger for most passages (like upright bassists often do).
