Learn Nocturne in B major, Op. 9 No. 3
The most elaborate of the three Op. 9 nocturnes — a 135-bar B major work whose opening lyricism is interrupted by a turbulent Agitato section before returning, more ornate than ever, to close in serene radiance. The interactive score and loop tool let you isolate the agitato middle section's running passages — and return to the opening B major lullaby as many times as you need before both feel equally at home.

About the piece
The nocturne that refuses to stay calm — Op. 9 No. 3 in B major.
The three Nocturnes of Op. 9 were published in 1832 and dedicated to Camille Pleyel's wife, Marie. The third, in B major, is the most structurally complex of the set and perhaps the most surprising: it opens with a singing, almost lullaby-like melody in 6/8, then without warning erupts into a passage marked agitato before returning to the opening calm — a shape that foreshadows the large-scale ternary nocturnes of Chopin's maturity.
Chopin learned the nocturne form from the Irish composer John Field, who invented it, but in Op. 9 No. 3 he already transforms it beyond recognition. The agitato section introduces rapid passagework and dramatic dynamic contrasts that Field never attempted. By the time the opening melody returns, it has acquired a fragility it did not have before — the calm sounds earned rather than given.
Practice path
Master the calm before confronting the storm.
Learn the opening B major section thoroughly before approaching the agitato. The contrast only works if both sections are secure — a shaky opening gives the stormy middle section nowhere to return from. Use the loop on the agitato passage at 50% tempo to learn the notes without tension.

Questions
Before you practice.
Short answers for learners and for searchers deciding whether this is the right version to start with.
01How does Chopin Nocturne Op. 9 No. 3 compare to No. 2 in difficulty?
No. 3 is significantly more demanding. Where No. 2 has a relatively clean melodic line and moderate ornamentation, No. 3 features a turbulent middle section, elaborate written ornaments in the return, and a wider range of expressive demands — it is firmly in advanced territory.
02What is the Agitato section in the Chopin Nocturne Op. 9 No. 3?
Around bar 66, the serene opening mood gives way to a passionate, faster Agitato passage in B minor — a dramatic contrast that Chopin resolves by returning to the main theme, now decorated with increasingly elaborate filigree.
How to use this V1
The return of the opening must sound inevitable.
At 60% tempo, loop the transition from the agitato back into the opening melody and listen for how the harmonic shift prepares the return. At 85%, play through the full nocturne and use wait-for-note mode at the recapitulation to ensure the melody's re-entry is unhurried. The final bars should sound like the storm was always going to pass.
