'''Seventh Chordschords''' extend our basic Root-3rd-5th triad chords by adding a 7th (R-3-5-7). This extra note adds an additional degree of harmonic complexity to chords. They can be used to strenghthen or weaken the resolve of cadences, as well as simply making things more interesting. It gives us a much greater variety of chords to choose from.

The '''Dominant Seventhdominant seventh''' is the most common 7th chord. It is the dominant 7th (V{{7}}) chord of the Major and Harmonic Minor scales. The m7 in the chord above the major triad enhances the tension of the dominant chord and its resolution to tonic. It contains the following intervals:
R M3 P5 m7

The '''Major Seventhmajor seventh''' is a fairly common 7th chord (also sometimes written as {{maj}}{{7}}). It appears as on the I and IV chords diatonic to the major keys. The M7 typically needs some space to prevent it from sounding overly dissonant. If the octave is stacked on top the M7, you get the inversion of the M7, the m2 interval, which is very dissonant. Overall, I find this chord sounds quite peaceful; however, it still has a bit of tension. This makes it work great for jazz or if you want to use the tonic without feeling fully resolved. It contains the following intervals:
R M3 P5 M7
