The perfect fifth is one of the most stable intervals in music. When you hold a fifth above a moving line, you're training your ear to lock onto the 3:2 frequency ratio that makes this interval so powerful and resonant.
This exercise has you sustain scale degree 5 while the backdrop ascends from 1 to 5. You'll experience changing intervals as the melody moves, but your job is to stay anchored on your note.
Actionable Step: Fifth Drone
1. The Sound
Use a tall "Oo" vowel with rounded lips. This darker, more focused vowel minimizes harmonic complexity and lets the acoustic relationship between the voices ring clearly. The lower formants of "Oo" complement the open character of the perfect fifth.
2. The Feel
When the backdrop starts on 1, you'll feel the pure resonance of a perfect fifth. As it moves through 2 and 3, the intervals become more complex. Scale degree 4 creates the most tension against your held 5. When the backdrop finally reaches 5, you'll feel the release of unison.
Pay attention to the moments when the interval locks in. At the start (1 against 5) and end (5 against 5), you should feel reduced effort and increased ringing. That sensation is what you're learning to recognize and maintain.
3. The Drill
The backdrop plays scale degrees 1-2-3-4-5 with half notes and a whole note ending. You sustain scale degree 5 throughout.
Backdrop (what you hear):
Your part (what you sing):
Think of your pitch as fixed while the backdrop rises beneath you. The moving line creates changing colors against your steady tone. Your job is to be the anchor.

Using the Fader
Start with the fader toward your harmony part so you can clearly hear the fifth you need to hold. As you gain confidence, gradually shift the fader toward the melody. The real challenge comes when the ascending line is louder than your guide track.
Pay attention to scale degree 4 in the backdrop. This creates a major second against your held 5, which is the most dissonant moment. If you can hold steady through that tension without pulling your pitch down, you've built genuine interval independence.
