What instruments did Claude Debussy compose for?

He wrote more piano works: a set of Études and a piano duet called En blanc et noir (In white and black). He planned to write six sonatas, each for a different group of instruments, but he only wrote three of them: one for cello and piano, one for flute, viola and harp and one for violin and piano.

How did Claude Debussy become a composer?

He was encouraged by an associate of Polish composer Frédéric Chopin, and in 1873 he entered the Paris Conservatory, where he studied piano and composition. While living in a poverty-stricken suburb of Paris, he unexpectedly came under the patronage of a Russian millionaire.
