The G7 (G dominant 7) chord contains the notes G, B, D and F. It is produced by taking the root (1), 3, 5 and b7 of the G Major scale. It is essentially an G chord, with an added flat 7.
G7 is a very common chord in all of music, because it is found in the key of C, which is in many ways the default key in much of music theory.
G7 is short for G dominant 7. The dominant 7 chord is a significant chord, because it plays a very important function in any given key.
The dominant 7 chord functions as a chord that resolves to the first chord in a key. For example, the G dominant 7 chord resolves to the C Major chord (which is the first chord in the key of C)
