The G major key signature
One of the reasons the key of G is so popular is because it is relatively easy for guitarists and other musicians to play. Part of this comes from the fact that it only has one sharp (F). Also, the finger position on the guitar frets is not overly complex. When reading sheet music, you can quickly identify G major from the sharp on the top line as seen below.

The rest of the notes in the scale are A, B, C, D, E, and F# at the top.
