LESSON 6

SECONDARY DOMINANTS 

    Ø  This lesson features the secondary dominants, these are chords that act as the dominant, but they are used to resolve chords other than the tonic. In most cases, they are used in half cadences, and in other cases, to prolong the tonic area.  

In this image, there are various secondary dominant chords and the tonicize-notes in a minor key.

 There are also various secondary dominant chords and the tonicize-notes but in a major key.

    Ø  In recognizing the secondary-dominant chord to the dominant, you would notice it is a second-degree chord transformed. In transforming this chord into a secondary dominant chord, the fourth degree is raised by a half step in major-keys, while in minor-keys, the fourth and sixth-degree raises by a half step. A minor third above the 5th of the chord further extends the chord to a V⁷.

This image shows the V⁷/V in the tonic area and how it resolves. It also shows the F sharp that does not belong to the diatonic also to notice how the F and F shop is in the same voice.

  Ø  Knowing that this chord is doing the actual job of the dominant, it must resolve like the dominant. The resolving of this chord involves two notes, the chordal 7^th, which is the first degree, and the raised 4^th degree, which acts as the leading tone.  The chordal 7^th moves down to the 7^th degree while the raised 4^th degree moves up to the fifth degree. Also, try to prevent doubling the acting leading tone.

In this image, the A major chord is the V/ii chord, and the C was raised by a semitone making it a major chord. The D chord is the tonicize chord that follows.

 Ø  Cross relation, this term is used to express the 4th degree of the diatonic in a voice, and the raise 4 degree suddenly follows in another voice. It is suggested for both pitches to be in the same voice. 

Ø  The secondary dominant can be any of the scale degrees other than the 5^th, 4th, and 6th in minor keys and the 4th and 5th in major keys. To locate the note, first, identify the tonicize note, which is the note that is going to act like the tonic. Then follow 2 1/2 steps down from the tonicize note, and there is your note. 

This melody is in three different keys with the chord progression of I, IV, V⁷/V, V, I in D and C major, and in D minor the chord progression of i, iv, V7/V, V, and i.

This is a performance of the melody above, with the chord progression in three different keys.
