Piano Concerto no. 5 in E flat major, op. 73, "Emperor"

The Piano Concerto No. 5 in E♭ major, Op. 73, known as the Emperor Concerto in English-speaking countries, is a piano concerto composed by Ludwig van Beethoven. Beethoven composed the concerto in 1809 under salary in Vienna, and he dedicated it to Archduke Rudolf, who was his patron, friend, and pupil. Its public premiere was on 28 November 1811 in Leipzig, with Friedrich Schneider as the soloist and Johann Philipp Christian Schulz conducting the Gewandhaus Orchestra. Beethoven, usually the soloist, could not perform due to declining hearing. The work's military aspects and symbolism characterize its heroic style. Beethoven used novel approaches with the piece, such as lengthening the concerto (it is approximately forty minutes long) and creating a new relationship between piano and orchestra. The first of its three movements, Allegro, is in sonata form and is longer than any opening movement of Beethoven's earlier piano concertos. The second movement, Adagio un poco mosso, is a nocturne that directly builds into the third movement. The last movement, Rondo: Allegro ma non troppo, is in seven-part rondo form. The origin of the epithet Emperor is uncertain; it may have been coined by Johann Baptist Cramer, the English publisher of the concerto. The concerto has no association with any emperor, and according to Donald Tovey and Betsy Schwarm, Beethoven would have disliked it due to his disapproval of Napoleon's conquest. As part of his repertoire, Franz Liszt frequently performed the concerto throughout his life. Since its first recording in 1912, it has been recorded numerous times by classical pianists.
