Every lesson opens with last week's subjects already in it, one for each thing you assigned, one for each piece they worked on, and whatever else you keep track of. Change what you want, leave the rest. No retyping the same paragraph every Thursday.

Lead their screen during the lesson, point at the music, send a tuner or a metronome to their device, and go straight from one sibling into the next without redialling.

The week's routine arrives on your device at your teacher's tempo with their notes attached. Press play and it walks you through it, one thing at a time, with the metronome, the tuner and the music all on one screen.

What your teacher wrote about each piece is right there while you play it.

Photograph a page or upload a PDF and it finds the lines, so you tap once instead of pinching. Beat dots, a tuner trace and the clock sit along the bottom, out of the way of the notes.

Hold a note in tune for ten seconds and the tuner line catches fire. Every session is counted, so the work is visible even on the weeks it does not feel like it.
