From knowing nothing to actually playingAn electric keyboard and digital piano course for complete beginners
Koh Key teaches electric keyboard and digital piano one day at a time. It reads like a book, and you can try every idea straight away — on screen or on your own MIDI keyboard. Every chapter has diagrams, exercises, and homework you can repeat as often as you like.
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.
A 72-day course, one chapter a day, with diagrams, exercises, and a read-aloud button.
Play along with falling notes. Toggle the guides, slow it down, loop the bar you keep missing.
Every chapter's homework in one place. Repeat it forever; weak items get pushed back to the top.
Play freely, plug in a MIDI keyboard, and watch a live readout of notes, chords, and intervals.
Ten games for your hands, ears, reading, and timing. Playable with or without a keyboard.

Six levels, seventy-two days
Each day takes about 30–55 minutes. Read it, try it for real, play the minigame, then take the homework away to practise.
Your instrument and your body
Before 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.
Rhythm and reading
Music is sound placed on time. This level gets your timing steady first, then teaches you to read the page.
Scales and keys
A 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.
Chords
Chords are several notes at once. This level runs from two-note intervals all the way to reading the chord chart of a real song.
Two hands, for real
Theory has to become sound. Left-hand patterns, the pedal, dynamics, and playing a whole song from chord symbols alone.
Advanced
The level that separates playing correctly from playing beautifully: richer harmony, harder rhythm, and how to practise so you actually improve.
The first 7 days are free, with no card
Read all seven chapters, play the keyboard, do the homework, and try every game. If you still want more by then, unlock the rest.
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.
