What is the difference between a major chord and a dominant chord?
A major 7th chord is formed by playing the root (1st) + 3rd + 5th + 7th notes of a major scale. A dominant 7th is formed by simply lowering the 7th note a half step. As an example, Cmaj7 = C – E – G – B (7th note). Lower the 7th note a half step, from B to Bb, thus Dominant 7th = C – E – G – Bb.
