Practice your students actually do

Short lessons in pitch, ear training and harmony that students do on their own, on a phone or a laptop. You hand out a song's part by link, and the app does the drilling.

A two-minute ear game for the class

Put it on the board: the guide sings a leap, the class calls out three, four or five, and you tap their answer. No mic and no accounts.

Now playingUnit 1, its challenge

Name that leap

You already carry these leaps in songs you know. The guide sings a leap up, from a new note each round: is it a three, a four or a five? Stuck? Hear the song that starts with it.

Songs that start with each leap

Which leap was it?

No mic here: you only listen. In lesson 1 you sing each leap back, and the app hears where you land.

From Ear training's first unit, its challenge. In the course, each student names the leaps, then sings each leap the screen asks, and the app hears where they land.

Lessons they can do alone

Each course is short lessons of a few minutes: landing on a note, naming and singing leaps, hearing major and minor, making up a harmony. Students hear a guide, sing it back, and see how close they were.

Hand out a part by link

Share a song's link and each student learns their part at home with a guide voice: their part louder, or the others singing while they fill it in.

Students under 18. There are no class groups or class sharing for students under 18: you lead, and each student uses the lessons and songs on their own. Students from 13 can sign up. Once we've approved you as a teacher, your class code gives each of your students Plus free for a year, and you see only how many seats are used, never who.
