Sing in Harmony: The 6-Day Program (Beta)

Hear two notes lock together, then sing the third, the fifth and the chord notes that make harmony. Free, no sign-up, and your progress stays on your device.

Who this is for

Anyone who wants to sing a second part, with a friend, a choir, a band or just for fun: complete beginners at harmony are welcome. If you can match a note you hear, you are ready. Already harmonise by ear? Test out on Day 6.

Best done after: Ear Training: Intervals, Intervals. It is advice, not a rule: every lesson has short "rusty on…?" boxes for anything you skipped.

Why learn this

Singing harmony sounds like a talent, but it is mostly two small skills: **hearing** the other note, and **staying on your own**. Both can be trained on your own, with no choir and no teacher, in small steps.

This program teaches the steps in order. First you learn what it sounds like when two notes lock together (a drone makes that easy to hear). Then the intervals that blend best, then a harmony a third from a melody, then the notes of a chord, then lines that move while the chords change. It is a **beta**: the microphone trainer works, and we are still tuning it, so tell us if something feels off. Music is fluid, and a wobbly note is information, not failure.

What you will be able to do

  • What it sounds like when two notes lock together
  • Singing the octave, the 5th and the sweet 3rd against a drone
  • Finding and singing a harmony a third or sixth from a melody
  • Splitting a chord between voices
  • Singing a line that glides through chord changes
  • Keeping your own part when others sing something different

The 6-day plan

  1. Hearing two notes lock together. Match a held note and hear the difference between locked and wobbling.
  2. The octave and the fifth. Sing a perfect 5th above a drone and hear when it locks.
  3. The third: the sweet one. Sing a major or minor third against a drone and name which it is.
  4. Harmony above a tune. Sing a harmony a third or sixth from a melody and stay on your line.
  5. The notes of a chord. Sing the root, the 3rd and the 5th of a chord, and a smooth line through changing chords.
  6. Keeping your own line. Hold a part while others sing something different, and pick the part that suits your voice.

How each session works

Every day follows the shape of a workout. It starts with a warm-up that reviews earlier days, then technique: a short, plain explanation with a small interactive tool to try it on. Then come the working sets, drills with instant feedback, and a finisher, a short test with a pass mark so you only build on things you can do. A cool-down recaps the day and previews the next.

Choose your split

The daily split is a session a day: done in a week. The easy split is a session every other day, with rest days between: two weeks, and a gentler pace. On your own pace there is no schedule. Nothing is ever locked, and you can change split at any time.

Frequently asked questions

I think I am a bad singer. Can I still do this?

Yes. The program only asks you to match a note, a skill almost everyone can learn. You can sing quietly, hum, or whisper-sing. Pitch gets better quickly with this kind of focused practice.

Do I need a microphone?

It helps, because it shows whether you are sharp or flat, but it is not required. Without one, hear the guide and sing along; the ear training is the same.

Do I need to read music?

No, though it helps. The program shows note names and the Harmony Finder shows the staff. If you are new to the staff, the Reading Music program is a good companion.

What are the headphones for?

Without them the microphone hears the guide as well as your voice and gets confused. With headphones it hears only you.

Is my voice recorded?

No. It is analysed on your device as you sing and then thrown away. Nothing is uploaded.
