Berklee Press: Chord Studies for Electric Bass

Morrighan,
what are suggested, are some possible fingerings for these notes. Some notes, almost all of them actually, can be found on different places on the fingerboard. So if you decide to play that C on the E string [first option], then the best option for the next note, E, is to play it on the A string, and similarly the note G on the D string. If you follow this direction you to not have to move your hand at all to play these 3 notes. You would play the C with your pinky, the E with the ring finger and the G with the index finger.
If you chose to play the C on the A string, 3rd fret, and want to follow the previous fingering from the E on, then you will have to shift your hand. I do not have the book in front of me, so I cannot be more accurate from this on, but the letters under the grades are the suggested strings where to find the notes.
