Note Pierce drill: which note is higher, on a piano keyboard in the side panel

160 levels. Six ways to listen.

Every module is a ladder. Start with the fundamentals and gradually move into more advanced harmony, interval recognition and rhythm training.

Intervals

11 levels

Start with higher-or-lower, then name what you hear.

Chords

27 levels

Chord qualities first, then harmony that keeps getting denser.

Scales

27 levels

Tell the sound and character of one scale from another.

Progressions

22 levels

Harmonic movement and function, not just chord names.

Inversions

54 levels

Hear a chord change when a different note sits in the bass.

Rhythm

19 levels

Choose the notation, tap along, or tap a bar back from memory.

Built to help you improve.

Build the drill you actually need

Two intervals you keep confusing. One rhythm that never lands. Pick exactly the material, root, direction, octave range, tempo, exercise mode, and more — then save it as “Modes I confuse” and come back whenever you need it.

A wrong answer does not just disappear

Note Pierce tracks the individual sounds you miss. Weak Spots shows what needs work. Review brings each one back when it is due, so you practice the thing you got wrong instead of repeating a whole lesson.

See what is actually getting better

Answers, accuracy, practice time, and a heatmap of how consistent you have been. Weekly, monthly, and yearly recaps you can save or share, and badges as you improve.

No guilt streaks

Miss a day and nothing gets erased. Set a practice reminder if you want one and ignore it if you do not. Five minutes between tasks still counts.

Practice with the sound you want

Free gives you E. Piano and hollow, plus nine rhythm sounds. Pro adds organ, sine, bowed, and acoustic and electric guitar recorded note by note — so you train on the timbre you actually play.

Your practice data stays yours

Everything lives on your device. No account to create, nothing to sign into. Export it, import it, or delete all of it whenever you want.

Close the feed. Open your ears.

No blank page wondering what to work on. Just listen, choose, learn what you missed, and come back a little better next time.

Hear it. Name it. Know it.
