The scale tone chords studied so far involve the placement of two notes (separated by an interval of a third) above a root note. This method of building scale tone chords can be extended by adding another note of a third interval, illustrated in the following table:
Here are the scale tone 7ths in C major played in root position.
The following example contains all seven scale tone 7ths in C major. The progression is I IV VII III VI II V I. The shapes used here are all close together on the fretboard. This makes them easy to play and results in a smoother sound than moving up and down one string to find the root notes of the chords.
