Open Major 7th Chords

Major 7th Chords are thought of as being 'jazzy' and are often used in jazz music.

Major 7th Chords tend to add more tension and dissonance to a chord progression than a major chord. They are often used to create a sense of movement and to create a sense of resolution to the tonic (or starting) chord.

Major 7th Chords are built from a major triad with an added major 7th interval.
