Claude Debussy (1862-1918) was a French composer who fundamentally reshaped how music could sound and function. Rather than following the rigid harmonic rules of his predecessors, Debussy treated harmony as color and gesture, letting timbre and sonority drive musical meaning. His approach influenced nearly every composer who followed, making him essential listening for anyone serious about understanding twentieth-century music.
Debussy's piano works remain central to teaching repertoire because they demonstrate how technical facility serves interpretive imagination. His scores reveal a composer equally interested in what the instrument can whisper as in what it can declare.
