Chopin’s Nocturne in C minor is among the finest of all his explorations of this form. More overtly dramatic than most of his other nocturnes, it begins with a solemn, halting melody in the right hand, supported by chords that have some of the characteristics of a funeral march. The result, though, is more lyrical and more plangent (reminding us of Chopin’s fondness for bel canto opera) than the austere tread of his most famous funeral march (in the B flat minor Sonata). The central section is a richly harmonized chorale in C major, that is – in due course –infiltrated and disturbed by a quicker, more chromatic figure in a triplet rhythm that eventually provokes an explosive climax – complete with Lisztian octaves – before the music turns back to the minor key, and the material from the opening. Here Chopin does something unexpected. The uneasy triplet rhythms that had disrupted the chorale are now transformed into a restless, agitated accompaniment for the melody, and it is only in the last two bars that the nervousness finally subsides.

This Nocturne was the first of a pair dedicated to a favourite Chopin pupil – Laure Duperré, the beautiful daughter of an admiral – and was first published in 1841 by Schlesinger in Paris. The following year, it was reviewed in the Revue et Gazette musicale by Maurice Bourges. Writing in the form of a letter to an unnamed Baroness, Bourges offers a description of the work’s design that was quite novel for the time outside the pages of composition treatises (Schumann was one of the few who had attempted something similar in the general musical press): ‘Here in a few words is an outline of the thirteenth nocturne. A first period, in C minor, is distinguished by the character of the melody that dominates it; the second, in C major, begins pianissimo; it belongs to the complex form that has been very aptly called melodic harmony; then it ends with a restatement of the first theme, accompanied this time by pulsating chords that give the general rhythm a new warmth.’
