Mirror motion creates a symmetrical relationship between two voices. When the melody goes up, you go down. When it goes down, you go up. The result is a beautiful contrary motion pattern that expands and contracts around a central axis.
This exercise trains you to maintain your own contour while hearing the opposite motion. The backdrop moves 1-3-1-5-1, alternating between ascending and descending. You sing the mirror: 5-3-5-1-5.
Actionable Step: Mirror
1. The Sound
Use an "Eh" vowel with forward, bright placement. This vowel choice helps you maintain clarity and identity as your line moves in opposition to the backdrop. Keep the resonance consistent throughout the exercise.
2. The Feel
The mirror relationship creates a fascinating sensation. When the backdrop ascends from 1 to 3, you descend from 5 to 3, meeting briefly at the third. Then the backdrop descends while you ascend. It's like watching a reflection that moves opposite to you.
The challenge is cognitive: your ear wants to follow the backdrop's motion. Resist this urge and commit to your own contour.
3. The Drill
The backdrop alternates: 1-3 (up), 3-1 (down), 1-5 (up), 5-1 (down). You mirror it: 5-3 (down), 3-5 (up), 5-1 (down), 1-5 (up).
Backdrop (what you hear):
Your part (what you sing):
Think of each interval as a reflection point. When you hear ascending motion, feel yourself descending. When you hear descending motion, feel yourself ascending.

Using the Fader
Start with the fader toward your harmony part so you can clearly hear your mirror line. As you gain confidence, shift the fader toward the melody. The real test is maintaining your contrary motion when the melody is more prominent.
Let the backdrop exist as background. Your job is to commit to your own contour, not to track both lines simultaneously.
