Claude Debussy was a French composer (1862-1918). He was among the most influential composers of the late 19th and early 20th centuries.
Suite bergamasque is one of Debussy’s most famous piano suites. It was first composed by Debussy around 1890, at the age of 28, but was significantly revised just before its publication in 1905. The third and most famous movement of Suite bergamasque is “Clair de lune”, written in the key of D♭ major. Its time signature is 98 and the music is marked andante très expressif meaning at a walking speed; very expressive. Listen out for the homophonic texture. This literally means ”sounding together”. The texture of a piece can be described as homophonic when several parts move together (e.g. in the same rhythm). A good example of this can be heard around 1 min 36.
