Just like Johann Sebastian Bach before him, Ludwig van Beethoven played a significant role in the development of the cello. His five sonatas for cello and piano, three cycles of variations and the Triple Concerto all enhanced the instrument's expressive scope to an extent that has not been bettered to date. With his unparalleled ability to endow the instrument with highly lyrical and elegantly cantabile qualities, he blazed the trail for composers who would follow him.
