VIII Pitch & the singing ear · Chapter 3
Singing intervals & scales
From single notes to distances — connecting your voice to the interval and scale theory you already know.
Once you can match single notes, the next step is distances: starting on one note and landing accurately on another. This is where the singing course joins hands with the theory you’ve already done — intervals and the major scale stop being diagrams and become something your body does.
Why singers drill intervals
A melody is nothing but a chain of intervals. When you miss a note mid-song, you almost never miss it as a pitch — you miss it as a jump: the fourth that came out as a third, the leap that landed short. Training intervals directly trains the jumps.
The classic method: anchor songs
Every interval lives at the start of some song you already know. The time-tested trick: borrow the song, keep the interval.
| Interval | Up |
|---|---|
| Minor 2nd | the Jaws theme |
| Major 2nd | ”Happy Birthday” (first two notes) |
| Minor 3rd | ”Greensleeves” |
| Major 3rd | ”Oh When the Saints” |
| Perfect 4th | ”Here Comes the Bride” |
| Perfect 5th | ”Twinkle Twinkle” |
| Octave | ”Somewhere Over the Rainbow” |
Sing the song’s opening; feel the size of the jump; then sing the jump without the song. After enough repetitions the interval stands on its own.
Drills with the pitch tool
Use the matcher below as your starting-note anchor:
- Interval echo — get a target note and match it. Now sing a major 2nd above it, then return to the target and check you’re still in tune. Work outward: 3rds, 4ths, 5ths.
- Scale walk — match a target in your low-middle range, then sing the major scale up five notes (do–re–mi–fa–sol) and walk back down. The test: when you land on do again, the needle should still read green. If you drifted, you’ll see exactly how far.
- Octave flip — match a note, sing its octave (the tool accepts any octave, so watch the needle stay centered), come back.

Recap
- Melodies are chains of intervals — train the jumps, not just the notes.
- Anchor songs give every interval a memory hook you already own.
- Use the tool for interval echoes, five-note scale walks, and octave flips; the return-to-do check exposes accumulated drift.
- This is the theory course’s interval chapter, made physical.
