Developing the ability to identify secondary dominant chords by ear is a crucial skill for musicians aiming to improve their harmonic awareness. These chords add color and tension to progressions, and recognizing them by ear enhances improvisation, transcription, and composition skills.
Understanding Secondary Dominant Chords
A secondary dominant is a chord that functions as a temporary dominant to a chord other than the tonic. It usually appears as a V or V7 chord targeting a diatonic chord within the key. Recognizing these chords by ear involves listening for their characteristic tension and resolution patterns.
Common Secondary Dominant Chords
- V7 of ii (V7/ii): Resolves to the ii chord, often heard as a dominant leading into the supertonic.
- V7 of iii (V7/iii): Targets the mediant, adding a sense of surprise or color.
- V7 of IV (V7/IV): Creates tension before moving to the subdominant.
- V7 of V (V7/V): A secondary dominant that leads to the dominant chord.
Ear Training Drills
1. Recognizing the Dominant Function
Play a simple chord progression in a major key, such as I–V–I. Then, insert a V7 chord that temporarily functions as a secondary dominant, such as V7/ii. Focus on the increased tension and the strong resolution to the target chord.
2. Isolate the Tension
Listen to the V7 chord without the resolution. Notice the leading tone (the seventh of the V7 chord) and the dominant seventh interval. Practice playing these chords on your instrument and singing them to internalize their sound.
3. Transcribe Progressions
Listen to recordings of progressions containing secondary dominants. Try to transcribe the chords by ear, focusing on the characteristic sound of the secondary dominant. Confirm your transcriptions with a keyboard or guitar.
4. Use a Call-and-Response Exercise
Play a progression that includes a secondary dominant, then pause and sing or hum the target chord. Reverse the exercise by playing the target chord and then singing the secondary dominant that leads into it.
Tips for Effective Ear Training
- Start slow: Use simple progressions and gradually increase complexity.
- Use reference recordings: Compare your listening with professional recordings.
- Consistent practice: Dedicate a few minutes daily to ear training exercises.
- Sing along: Vocalizing helps internalize the sound of secondary dominants.
By regularly practicing these drills, musicians can improve their ability to identify secondary dominant chords by ear, enriching their harmonic understanding and improvisational skills.
