Guitar Seventh Chords

There are a couple types of ways to play a 7th chord on guitar.

A Major 7 (Maj7) chord is played with the normal chord formula and adding one more note to the mix: the 1st or root note, the 3rd, the 5th, and natural 7th notes of a major scale.

A Dominant Seventh (7) chord is played by using the flat(♭) 7th note of the major scale.
