Title : Frederic Chopin ,Polonaise in A, Op.40 No.1, 'Military'<br /><br />From Wikipedia,<br />The Polonaise in A-flat major, Op. 53 or (French: Polonaise héroïque, Heroic Polonaise) was written by Frédéric Chopin in 1842 for solo piano. This masterpiece is one of Chopin's most popular compositions and is still a current favorite of the classical pianoforte repertoire. The piece requires exceptional pianistic skills and requires virtuosity in order to be played at an appropriate level of quality.<br /><br />Although the piece is labeled as a polonaise, it has little to do with the typical polonaise style. It presents two sections with a polonaise rhythm, but most of it has no particular polonaise attribute. It has been said that Chopin had composed the piece having a free and powerful Poland in mind, which may have led him to label it as a Polonaise.
