The nocturne almost everyone learns first, written when Chopin was barely twenty.
Chopin wrote the three nocturnes of Op. 9 in his early twenties, around the time he left Poland for Paris, and published them in 1832. The form was not his invention — the Irish composer John Field had established the nocturne a generation earlier: a singing right hand over a spread left-hand accompaniment. Chopin made it his own and returned to it for the rest of his life, twenty-one times in all. The E♭ major is the second of the set and by a distance the most played.
It runs a little over four minutes. A single melody is stated three times in 12/8 over a left hand that rocks between a low bass note and the chord above it. What changes is the decoration: each return of the tune is more elaborate than the last — turns, added grace notes, a run that spills over the bar — until the final page opens into a long cadenza-like flourish and a quiet cadence. The ornaments are written out, but they were meant to sound improvised.
The left hand is the real work. It has to leap from the bass note up to the chord and back, a swing that often reaches a tenth or more, roughly eleven times a bar, quietly and in time, while the right hand sings freely above it. Chopin’s rubato depends on that accompaniment staying steady, so the two hands are doing genuinely different jobs. The right hand’s ornaments look worse on the page than they sound: most of them are fitted into a beat you already know.
This is one of the pieces the app has arranged across levels, and the reduction aims straight at the left hand — from about eleven attacks a bar down to two at the beginner level: a bass note and a chord you take once and hold. The melody stays as Chopin wrote it. Hands apart first, then slowly together, is the same route a teacher would give you.
This is one of the pieces we have arranged into levels — the same music, thinned out, so you can start it long before you can play it whole. Every note in an easier level is a note the composer wrote; nothing is moved or rewritten. Not every piece supports all four rungs, and the app tells you which ones this piece has.
