The three Polonaises, Op. 71 were composed by Frédéric Chopin in his earlier days.
After the death of the composer, Julian Fontana had made up their summaries and publications. These works were published in 1855, and are now often designated as Nos. 8, 9 & 10 in the order below, continuing the numbering system followed by the seven polonaises published during the composer's lifetime.
Like most of Chopin's polonaises, they are in ternary form.
