All fretted C’s on the E, A, D strings

Play this tab exactly—

C power chords, major barre chords, and minor barre chords

Are you able to play all C’s confidently and without error? If so, then play the 3 G’s, 3 A’s, 3 B’s, and then the 3 C’s. Do this exercise 20 times every day until you have mastered it.

Once you can perform this exercise 3 times in a row without error (at any speed) then you can move on to the next chapter (D).
