Ludwig van Beethoven (baptized 17 December 1770 – 26 March 1827) was a German composer and pianist. A crucial figure in the transition between the Classical and Romantic eras in Western art music, he remains one of the most famous and influential composers of all time.
Born in Bonn, then the capital of the Electorate of Cologne and part of the Holy Roman Empire, Beethoven moved to Vienna in his early 20s, studying with Joseph Haydn and quickly gaining a reputation as a virtuoso pianist. His hearing began to deteriorate in the late 1790s, yet he continued to compose, conduct, and perform, even after becoming completely deaf.
Beethoven is acknowledged as one of the giants of classical music; occasionally he is referred to as one of the "three Bs" (along with Bach and Brahms) who epitomise that tradition. He was also a pivotal figure in the transition from the 18th century musical classicism to 19th century romanticism, and his influence on subsequent generations of composers was profound.
Beethoven composed in several musical genres and for a variety of instrument combinations. His works for symphony orchestra include nine symphonies (the Ninth Symphony includes a chorus), and about a dozen pieces of "occasional" music. He wrote seven concerti for one or more soloists and orchestra, as well as four shorter works that include soloists accompanied by orchestra. His only opera is Fidelio; other vocal works with orchestral accompaniment include two masses and a number of shorter works.
His large body of compositions for piano includes 32 piano sonatas and numerous shorter pieces, including arrangements of some of his other works. Works with piano accompaniment include 10 violin sonatas, 5 cello sonatas, and a sonata for French horn, as well as numerous lieder.
Beethoven also wrote a significant quantity of chamber music. In addition to 16 string quartets, he wrote five works for string quintet, seven for piano trio, five for string trio, and more than a dozen works for various combinations of wind instruments.
