Piano, through the structure of songs
Learn the songs you love, by understanding how they're built.
Drop in a MIDI file or a score, or pick a tune from the library. Wolfi maps it out (chords, form, tricky passages) and prepares a half-hour session for each day, until you can play it from memory.
No sign-up needed: pick a song and start playing.
How it works
-
1
Bring your song
A MIDI file, a MusicXML score (MuseScore's export) or a tune from the royalty-free library.
-
2
Wolfi maps it out
Key, chord chart, form (A A B A…), recurring sections and tricky passages: you see how the song is built before you play a single note.
-
3
One session a day
Listen, lay down the chords, each hand phrase by phrase, then both hands in one go. Half an hour, and the next day opens tomorrow.
Everything to learn, nothing to distract you
The map of the song
Chords, form and sections in color: you always know where you are.
A tailor-made program
Based on how hard the song really is: more time for the busy passages, less for what comes back.
Falling notes, score, keyboard
Notes fall towards their keys, the score scrolls and the keyboard lights up what to play.
Checked on your MIDI keyboard
Plug in your digital piano: Wolfi listens and tells you what's right and what still needs work.
Built for memory
Phrase by phrase, yesterday's recap, passages played from memory: you remember what you understand.
One day at a time
The next day opens tomorrow: your memory keeps working while you rest.

About
Hi, I'm Julien.
Software development and the piano are my two passions. Wolfi was born where they meet: a tool I first wrote for myself, to learn my songs by understanding how they're built rather than repeating them note by note.
Wolfi is an independent project that I use at the piano every day. Your feedback helps it grow.
Frequently asked questions
Do I need a MIDI keyboard?
No. The on-screen piano, the falling notes and the score all work without one, and you can even tap the notes on the screen. With a MIDI keyboard plugged in (Chrome or Edge on a computer, Chrome on an Android tablet), Wolfi also listens to what you play and tells you what's right.
Where do I find a file for a song?
Many scores exist in MusicXML: in MuseScore, File › Export. A MIDI file works too. Otherwise, start with the free library.
What level is it for?
From someone who knows their first chords to someone coming back to the piano after years: the program adapts to how hard the song really is.
Which devices?
In your browser, on a computer, tablet or phone, with nothing to install. Best of all: a tablet on the music stand.
Can I cancel my subscription?
Yes, anytime, from "My account". Premium stays open until the end of the period you paid for.
Does Wolfi speak my language?
The website and your account do. The app itself (program, tips, quizzes) is in French for now; English is next.
What about copyright?
The library only contains public-domain works, encoded by me. The files you import stay private, for your personal use.
