The Library
Every piece is playable in-browser. Filter by level or mood, search by name, then open one and press play.
The DoReDog library holds 2,400+ pieces of piano music — from Bach and Mozart to Chopin, Joplin and Satie — every one written in colour‑coded letter notes and playable right in your browser. There's no sheet music to read and no sign‑up: open any piece, press play, slow it down, loop a tricky bar, and start learning by ear.
Every piece is in the public domain, so it's completely free. Use the filters below to narrow by difficulty or mood, or the search box to find a piece by name. New here? Start with the easiest classical pieces for beginners, or learn how letter notes work in two minutes.
What is actually in here
2,435 pieces by 435 composers — about 97 hours of music. Every one of them has been transcribed into letter notes: no stave, no key signature, no clef. A lowercase letter is a white key, a capital is the black key above it, the number at the start of the line tells you which octave, and a dash means hold or wait. That is the entire system, and it is why someone who has never read music can sit down and play Satie's Gymnopédie No. 1 — a piece written in a key with five flats — without ever learning what a flat is.
Why it is all old music
Everything here is in the public domain, and that is a deliberate constraint rather than a shortcut. Public domain means the copyright has expired, so the music can be transcribed, played, downloaded and printed by anyone without a licence or a fee. It also means the collection stops somewhere around the early 20th century — you will find Joplin's rags and Debussy's preludes, and you will not find anything from a film score or a pop record. What you get in exchange is a library that is genuinely free, permanently, with nothing behind a sign-up.
How the difficulty ratings work
Three levels, judged on what the piece asks of your hands rather than on its reputation:
- Easy (239 pieces) — a melody that mostly stays inside a five-finger span, a left hand that holds simple chords or single notes, and no fast passagework. Playable in a first week.
- Medium (1,380 pieces) — hands move around the keyboard, both hands have something to do, and there are passages you will need to practise slowly before they run at speed.
- Hard (816 pieces) — wide stretches, rapid figuration, three or more independent voices, or all of those at once. These are worth opening anyway: the slow-down control goes low enough that you can hear how a Chopin étude is built even if you cannot play it yet.
The ratings describe the transcription in front of you, not the concert performance. A piece can be famous and still be easy — and a forgotten Lied can be surprisingly awkward. They are not guesses either: every transcription in the library is measured for how fast it moves, how far one hand has to stretch, how many notes land under a hand at once and how much of it is black keys, and the label follows those numbers.
How to find something to play
The search box matches titles and composer names, and ignores accents: type fur elise and you will find Für Elise. The dropdowns narrow by composer, by period, and by mood. If you would rather be led than search, the collections group the library eighteen ways — First Steps, Calm Evening, Wedding & Ceremony, Christmas, Ragtime Parlour, Women Composers and more.
Two suggestions for a first piece. If you want something you already know: Ode to Joy — nine notes, no leaps. If you want something that sounds far harder than it is: Gymnopédie No. 1. And if you want the format explained properly before you start, the two-minute guide covers everything above in more detail.
What you can do with a piece once you open it
Every piece page carries the same toolkit: play and pause, a speed control that goes down far enough to sight-read at, an A–B loop for the two bars that keep going wrong, hands-separate practice, transpose, a metronome with count-in, a falling-notes learning mode, and a full-screen cinema view. You can download the piece as a MIDI file to open in any music software, or print a clean letter-note sheet to put on the stand. None of it requires an account.
