The classical training room
The complete training of a musician.
Counterpoint, harmony, ear training and the whole rest of the craft — taught in order, each answer weighed against the rules of the art. From your first interval to a fugue of your own and beyond.
For the complete beginner and the seasoned musician alike — a short placement starts you exactly where you belong.

Sixteen tracks, one curriculum
Every discipline a classical musician is expected to command, arranged as a single course of study.
The course begins with first intervals and ends in fugue. Between them lie species counterpoint, chromatic harmony, the instruments of the orchestra and the analysis of sonata form — more than 2,100 graded levels in all. Each unit opens with an illustrated reading chapter, the Rulebook, so the idea is on the page before the first exercise begins. Follow one track from end to end, or work across all sixteen — and if you already command a unit, sit its exam and test straight out of it.
Real repertoire
Bach himself, bar by bar.
Three hundred and forty-eight of Bach's chorales and all ninety-six preludes and fugues of the Well-Tempered Clavier, engraved on a real staff and analysed bar by bar. Name the cadence. Reduce a prelude to its harmonic skeleton. Harmonise a soprano as he did, and be graded against his own realisation. The repertoire the conservatory studies — here you study it too.
How it teaches
The methods of the old academy, carried out with the patience of a machine.
Engraved, not gamified
Exercises appear as real notation, elegantly engraved. Your writing is examined the way a teacher examines it — parallel fifths and octaves, a hidden fifth in the outer voices, an unresolved seventh or leading tone, a doubled third — each caught by name, with the reason it matters.
Ear first
Scale-degree hearing, melodic dictation on a real staff, chords identified blind. Listening drills are generated fresh each time, so you learn the sound rather than the answer key.
Hands on
Answer at the on-screen piano or connect a MIDI keyboard. Tap rhythms in time. At the tuning bench, you set the temperament by ear, one interval at a time.
Learning science, quietly
Spaced repetition, placement tests, adaptive practice and mastery tracking work in the background. You simply practice; the system remembers what you have earned and what needs review.
Exams & certificates
Each track closes with a final examination covering the whole course of study. Pass it, and the certificate is yours.
Your pace, your pitch
Slow the playback or press it forward, choose among five instrument sounds, and work in US or European note names, as you were taught.
A teacher in the room
You are never practising alone.
Mademoiselle — an elder teacher in the great pedagogical tradition — designs your path from a short listening diagnostic, then stays beside you: a word of method before a hard idea, a reason when an answer is wrong, a quiet nudge toward the key that frightens you. Rigour, warmly delivered.
Attention is not the door to the work. It is the work.
Mademoiselle
The free tools
Four instruments of daily practice, free forever. No account, no signup.
I was obliged to be industrious. Whoever is equally industrious will succeed equally well.
