The two Nocturnes, Op 55 by Frédéric Chopin, the fifteenth and sixteenth of his nocturnes, were composed between 1842 and 1844, and published in August 1844. The second nocturne, the Nocturne No. 16 in E flat major, differs in form from the other nocturnes in that it has no contrasting second section, the melody flowing onward from beginning to end in a uniform manner. – Martha Argerich
