Two ways to train with your MIDI keyboard: a new short piece to sight-read every day, the same for everyone, and a flashcard game to learn to read the notes on the staff. Free, in the browser.
A new short piece every day, in three tiers, with three attempts per tier and a star score to share.
Flashcards for the staff: a note appears, you play it on your piano or on the on-screen keyboard, with or without the clock.
