Claude Debussy was a famous French composer who lived from 1862 to 1918. He is known for creating a new style of music called impressionism, inspired by the art movement of the same name.

Debussy started studying music when he was very young and became a skilled pianist and composer. He wrote many beautiful pieces of music that were very different from those that had come before him.

Debussy's music was very atmospheric and dreamlike. He used lots of different techniques to make the music sound like it was floating or shimmering. He also loved to use unusual scales and chords, which made his music sound mysterious and unpredictable.

One of Debussy's most famous pieces is "Clair de Lune," which means "moonlight" in French. This piece is lovely and peaceful; it sounds like the moonlight shines on a quiet, peaceful scene.

Debussy also wrote music that was inspired by nature. For example, his piece "La Mer" (which means "The Sea" in French) is a symphony that captures the movement and moods of the ocean.

Debussy's music was prevalent during his lifetime, and it continues to be loved by many people today. He was a true pioneer and his innovative style paved the way for many other composers to experiment with new sounds and techniques.
