Ear training is a fundamental skill for musicians and students of music theory. One important aspect of ear training involves recognizing secondary dominants within melodies and chord progressions. These chords add tension and color, and understanding them enhances musical analysis and improvisation.
What Are Secondary Dominants?
Secondary dominants are chords that function as the dominant (V) of a chord other than the tonic. They temporarily tonicize a different degree of the scale, creating a sense of tension and release. For example, in the key of C major, the chord D7 can act as the V of G, making G the temporary tonic.
Identifying Secondary Dominants in Melodies
When listening to melodies, secondary dominants often appear as chords that lead smoothly into a target chord. They create a strong pull towards a specific harmony, often characterized by a dominant seventh sound resolving to the chord it tonicizes.
Listening Tips
- Listen for a chord that has a dominant seventh quality, especially if it precedes a chord a fifth above.
- Notice if the harmony creates a temporary sense of tension that resolves to a different chord than the tonic.
- Pay attention to the bass movement; secondary dominants often involve a V7 chord leading to the target.
Recognizing Secondary Dominants in Chord Progressions
In chord progressions, secondary dominants are often inserted before diatonic chords to emphasize them. These chords can be identified by their dominant seventh quality and their function as V of a chord other than I.
Examples in Common Progressions
- In the progression: C – D7 – G – C, the D7 is the V7 of G, a secondary dominant.
- In the progression: C – E7 – Am, the E7 acts as the V7 of A, highlighting the A minor chord.
- In jazz or pop, you might see chords like A7 leading to D minor, functioning as V7 of D minor.
Practicing Ear Training for Secondary Dominants
To improve your ability to recognize secondary dominants, practice listening exercises that focus on identifying dominant seventh chords resolving to target chords. Use a piano or a digital tuner to verify your guesses and develop aural skills.
Exercise Suggestions
- Play simple progressions and try to identify the secondary dominants by ear.
- Sing the bass line and listen for the characteristic V7 to I resolution.
- Use ear training apps or software that include secondary dominant exercises.
Mastering the recognition of secondary dominants enhances your overall musical understanding and improvisational skills. With consistent practice, you’ll be able to hear these colorful chords and appreciate their role in music.
