Claude Debussy was an influential French composer of the late 19th and early 20th centuries. His experimentation with music form, tonality, rhythm, and harmony helped define the style of Impressionism, a style of music that evokes a mood or an emotion without any direct reference to an image. But his innovations also extended to the scoring of his music, often making use of unusual instrumentations and combinations of instruments to create a specific atmosphere.

So, what does Debussy’s music tend to? His music is often characterised by its use of the full orchestra, for massive effects and multiple layers of sound. He also had a great fondness for using unusual textures, and would often combine instruments from different families, for example, wind and strings, or flutes and percussion in a single piece. He also liked to use tonal clusters to create walls of sound in his music, and was one of the first composers to experiment with aleatoric techniques, a kind of musical free-form improvisation.

Debussy also tended to use more traditional forms, such as sonatas and rondos, but he often transcended the boundaries of traditional composition by rearranging the elements of the form. He was also one of the first to employ twelve-tone compositional techniques, which allowed him to control and arrange the different elements of his music in an entirely new way.

Overall, Debussy’s music tends to defy categorization, as it combines traditional forms with unique approaches and instrumentation. He was a master of manipulating musical textur, and his experimentation with tonality, rhythm, and harmony helped create a unique and captivating musical style.
