The five places you'll spend your time
Read, practise, do the homework, play freely, and compete with yourself. They all feed one another, and progress from every page lands in the same place.
Lessons
A 72-day course, one chapter a day, with diagrams, exercises, and a read-aloud button.
Keyboard
Play freely, plug in a MIDI keyboard, and watch a live readout of notes, chords, and intervals.
Practice
Play along with falling notes. Toggle the guides, slow it down, loop the bar you keep missing.
Homework
Every chapter's homework in one place. Repeat it forever; weak items get pushed back to the top.
Games
Ten games for your hands, ears, reading, and timing. Playable with or without a keyboard.
And a set of tools

Chapters you can try as you read them
Every day is a written chapter with diagrams, a keyboard to play along on without leaving the page, and a read-aloud button on every section. Stop anywhere and pick it up from there.
Open day 1
The keyboard on screen, or the one you own
Play it with a mouse, with your computer keys, or plug a MIDI keyboard in over USB and play the real instrument. Either way the site names the note and the chord while you are still holding it.
Try the keyboard
Minigames that drill what you just read
Catch the note, pick the chord out by ear, run the scale, tap the rhythm. Short games that keep score — and bring whatever you are weakest at back around for another go.

Each day takes about 30–55 minutes. Read it, try it for real, play the minigame, then take the homework away to practise.
- Days 1–6Your instrument and your bodyBefore you can play you need to know what is in front of you, what each key is called, and how to sit so you can play for an hour without hurting.Start this level
- Days 7–18Rhythm and readingMusic is sound placed on time. This level gets your timing steady first, then teaches you to read the page. By the end you can open sheet music for a piece you want to play and work it out yourself, instead of waiting to be taught one song at a time.Start this level
- Days 19–30Scales and keysA scale is a set of notes that belong together. Learn the formula and you can build one in any key — and finally understand why a song sounds like it holds together.Start this level
- Days 31–44ChordsChords are several notes at once. This level runs from two-note intervals all the way to reading the chord chart of a real song.Start this level
- Days 45–58Two hands, for realTheory has to become sound. Left-hand patterns, the pedal, dynamics, and playing a whole song from chord symbols alone.Start this level
- Days 59–72AdvancedThe level that separates playing correctly from playing beautifully: richer harmony, harder rhythm, and how to practise so you actually improve.Start this level

What people ask before starting
Can I start without a keyboard?
Yes. Every chapter has an on-screen keyboard you can play with a mouse or your computer keys. Once you reach the chapters about finger weight and hand position, though, a real instrument helps a lot.
What is the difference between an electric keyboard and a digital piano?
A digital piano weights its keys to feel close to an acoustic piano and usually has all 88. An electric keyboard has lighter keys and fewer of them, but far more sounds and features. Day 1 covers this properly, and it is free to read.
I have never read music. Is this still for me?
The course is written for people starting from nothing. The first two levels cover the instrument, your hands, and keeping time — reading notes comes after that. No chapter assumes anything an earlier one has not taught.
Can I connect a MIDI keyboard?
Yes, in any browser that supports Web MIDI. Plug in over USB and play on the real instrument throughout the lessons, the practice page, and the games. Nothing to install.
How long does a day take?
About 30–55 minutes per chapter, including reading it, trying it, playing the minigame, and picking up the homework. Every homework item stays on the homework page, repeatable as often as you like, so you can split it across sittings.
