Born in Bonn in 1770, the eldest son of a singer in the Kapelle of the Archbishop-Elector of Cologne and grandson of the Archbishop’s Kapellmeister, Beethoven moved in 1792 to Vienna. There he had some lessons from Haydn and others, quickly establishing himself as a remarkable keyboard player and original composer. By 1815 increasing deafness had made public performance impossible and accentuated existing eccentricities of character, patiently tolerated by a series of rich patrons and his royal pupil the Archduke Rudolph. Beethoven did much to enlarge the possibilities of music and widen the horizons of later generations of composers. To his contemporaries he was sometimes a controversial figure, making heavy demands on listeners by both the length and the complexity of his writing, as he explored new fields of music.
