To play a Dominant 7th, take a major chord and add a minor 7th. That's 7 intervals, but the minor note, which is a semitone lower, flat note. For C Major this would be C – E – G – Bb. Dominant 7th chords are traditionally common in Blues music, and therefore Rock music too.
How do you get a dominant 7?
Playing the dominant 7th chord is easy. Just play a major chord, and add a note that is an interval of a minor 7th from the root note of the chord. Another way to think about it is by using a formula of half steps.
What is the structure of a dominant 7th chord?
A dominant seventh chord consists of the dominant triad (fifth note of the scale is the root of the dominant chord) and an added note a minor seventh above the root. For example, the dominant seventh chord in C major (or minor) is G-B-D-F.
