4/4 Time simply refers to the amount of beats per measure. 4/4 time, as the name implies, has 4 beats per measure. 1, 2, 3, 4, 1, 2, 3, 4, 1, 2, 3……
A chord progression might look something like this on paper.

G / / / | / / / C / / / | / / / D / / / | / / / G / / / | / / /

Each letter or line represents one beat. G, C, D and G each equal one beat. Each / equals one beat and each | equals one beat. There is a letter and 7 lines before from to G to C.
So you would play eight beats (two measures) of G than play two measures of C. After C you would play 2 measures of D then G. Try counting 1, 2, 3, 4, to some songs on the radio you will be surprised to see how many songs use 4/4 time. I have personally found playing my guitar while listening to drum beats has really improved my skill as a guitarist. Now whenever I play my guitar, whether I am playing rhythm or soloing, I always play along with drum beats.

I highly recommend using some of our free 4/4 time drumbeats that are an excellent practice tool for guitarist of any skill level.
