Movement I · The course
Eleven levels.
One honest ladder.
The ladder climbs from five notes around middle C to full grand-staff chords. Every level is open from day one: progression is shown, never gated.
Take a level's twenty-question test to earn a score. 80% passes and earns a star, 90% two, 100% three. Your best score sits right on each practice level, so you always know where you stand.
Begin at level one- I
Middle C & Friends
Five notes climbing up from middle C in the treble clef.
- II
Treble Staff
Every line and space of the treble staff, E4 up to F5.
- III
Treble Heights
Ledger lines above the treble staff, G5 up to C6.
- IV
Bass Clef Basics
Meet the bass clef: five notes stepping down from middle C.
- V
Bass Staff
Every line and space of the bass staff, G2 up to A3.
- VI
Bass Depths
Ledger lines below the bass staff, C2 up to F2.
- VII
The Grand Staff
Both clefs together: everything from C2 to C6, mixed.
- VIII
Sharps & Flats
Accidentals across both staves: the black keys join in.
- IX
Key Signatures
Sharps and flats move to the start of the line, where real music keeps them.
- X
Intervals
Two notes at once: read the distance as a shape.
- XI
Chords
Root-position triads: three stacked thirds read as one shape.
Movement II · Practice
Practice that notices what you miss.
Adaptive drilling watches every answer. Miss a note twice and it starts coming back more often, with an unaided retry a few rounds later. Master it and it quietly steps aside. Nothing here is graded: peek whenever you like.
The deck stacks itself
Each note carries a weight built from your accuracy and speed. G4 giving you trouble? G4 is what you'll see. The moment it sticks, the weight melts away.

Movement III · Songs
Real tunes,
one note at a time.
Thirteen intro songs teach reading the way songs always have: the glowing note is next, play it to move on. Easiest first, in both clefs, with grand-staff pieces waiting at the end of the list.
Finish a song once and its in-tempo mode unlocks: the same melody, now flowing at real speed while you keep up.
Open Intro SongsThe glowing note is next
Ode to Joy opens the list. Play the lit note and the highlight moves on; miss it and the song waits for you.

Movement IV · The Studio
The Studio.
Every player has a room where the real work happens. Yours is built in: load a YouTube performance, a MusicXML or MIDI score, or both synced together, then slow the piece down, loop the hard bars and scrub through it while the sheet and the falling notes track the video to the frame.
Inside the Studio
Frame steps, slow motion, section loops, pinned timestamps. The sheet flows past a fixed playhead; drag anywhere to scrub and hear each note the marker crosses. Click a note to hear just that note.

Falling notes, if you prefer
The same score as a piano roll: right hand in jade, left in ember, landing on the keys in sync with the sheet and the video.
Your markings travel
Pins, sync points, the score and your notes ride with each song: synced to your account, and saved to a single song file you can hand to a friend.
Open the StudioMovement V · Rhythm
Rhythm is half of reading.
Pitch tells you which key. Rhythm tells you when, and it's the half most courses skip. Here you tap patterns of notes and rests against a metronome, scored on how close to the beat each tap lands.
Timing windows tighten as you level up, one stray tap is forgiven per run, and your accuracy is measured per note, not per bar, so you can see exactly which beat keeps slipping.
Movement VI · Proof
When you're ready, prove it.
Practice is soft. Tests are not: one try per question, the clock running, and only finished runs count. Ended early? Discarded, never recorded.
The Test
One graded pass over a level: twenty questions, one try each, against the clock. 80% earns the star.
The Sprint
Sixty seconds, as many correct reads as your eyes can feed your hands. Medals for pace, boards for bragging.
The Reading Exam
Ninety seconds across everything you've learned, distilled into one fluency rating that climbs a ladder of ranks.
Crowns for fluent notes, stars for passed levels, medals for sprints: all of it feeds the shared leaderboards. Anonymous by default, your verified name if you sign in, a country flag if you choose one.
Movement VII · Your instrument
Bring your own piano.
Every mode is answered on keys. Which keys is up to you.
Touch
The on-screen piano works everywhere: phones, tablets, laptops. Scroll it, resize it, play it with your fingers.
MIDI
Plug in a keyboard on Chrome or Edge and answer on weighted keys. Reading real notation at real keys is the skill itself.
Microphone
No cable? Play your acoustic or electric piano out loud: the mic hears each note and presses the key for you. Works on Android and iOS.
