Nocturne Op. 27 No. 2

The second of Chopin's Op. 27 Nocturnes is less famous than the first and considerably more harmonically adventurous — which is why pianists and theorists tend to prize it above the more popular companion. It opens in D-flat major, a key Chopin associated with particular warmth and luminosity, and the left hand's accompaniment has an unusual flowing quality, crossing over itself in ways that blur the distinction between bass and inner voice. The melody is more overtly operatic than the Op. 9 No. 2, with longer phrases that arch upward and then float down, the right hand occasionally doubling in thirds or sixths to thicken the vocal line. The middle section moves into C-sharp minor and briefly intensifies before the main melody returns, now more lavishly ornamented — specifically, a long descending chromatic trill passage in the right hand that is technically demanding but sounds inevitable rather than showy. Near the end, Chopin introduces an ascending chromatic scale in the bass beneath the held final melody notes, giving the conclusion a quality of gradual illumination rather than simple cadence. This nocturne is introspective without being withdrawn, warm without being sentimental. It rewards attentive listening in a quiet room with excellent piano reproduction; the inner voices and harmonic movement get lost in casual settings.
