Lesson 1, without the app. It takes a minute.

  1. Hum a note: not too high, not too low.
  2. Find where it's easy: no push, no strain.
  3. Sing it on "oo", soft and steady, and hold it for a few seconds.
  4. That's your comfortable note. Every voice has an easy note, and there's no wrong one.

In the app, lesson 1 hears your note, names it, and shows the parts that may suit your voice.

Questions

Is it really free?

Units 1 to 7 are free, from your first note to all four parts of Amazing Grace. Plus opens unit 8, Expression, and the Plus courses.

Do I need an account?

No. You can start without one, and your progress stays on this device. A free account saves it to your account.

Can I learn harmony if I've never sung?

Yes, that's what it's for. The first units find your voice and steady your notes before any harmony.

Do I need to read music?
