Similar to Impressionist works in painting, many of Debussy's compositions attempt to express "light and shadow" and "color" through sound. He succeeded in creating a unique expression by employing free harmonies and modes that transcended the framework of functional harmony and tonality, which had developed from the late 17th century through the Romantic period. This piece, "Rêverie," composed in 1890, is a relatively early piano work by Debussy. As its title suggests, it is a very impressive short piece characterized by a beautiful melody enveloped in fantastic harmonies and a fade-out ending. Due to its beauty, this work has also been arranged for jazz and mood music, and has been enjoyed in various forms.
