Lesson 11—The Dominant Seventh Chord
In this lesson we will study the dominant seventh chord. This chord has the dominant chord as its base and then adds the seventh note of the scale, making a chord of four tones.
The dominant seventh chord is made up of the intervals of a major third, a perfect fifth and a minor seventh.
This chord can have four different positions, because it has four different tones. Study the examples below.
The seventh chord needs to be resolved to the tonic chord as follows: F of the Dominant 7th leads or resolves to the E in the Tonic Chord, B leads to C, D leads to C and G is retained as the binding tone, unless it is written in the bass.
In the exercise above, place lines from the notes of the dominant seventh chord to the notes in the tonic chord to which each resolves.
We have just studied how to resolve the dominant seventh chord. Now we will learn to go from the subdominant to the dominant seventh chord, and then resolve the dominant chord to the tonic chord. Notice that in going from the subdominant to the dominant chord, the F is retained.
Play these on the piano. Listen to the resolutions.
Harmonize the following exercises. Be very careful to observe strictly the chord resolutions and positions given above. There are some other possible positions and chord resolutions that are given before the exercises.
The figure (7) means that the dominant seventh chord is to be used. The dash after a figure means that the chord is continued.
