Claude DEBUSSY was a French composer. He is sometimes seen as the first Impressionist composer, although he vigorously rejected the term. He was among the most influential composers of the late 19th and early 20th centuries.(Wikipedia)
"Debussy (1862-1918) was – and still is – known for his innovative music. During his life, the Romantic Era was coming to a close. Composers everywhere explored new ways to create sound and atmosphere in their music. Debussy led the way in using music as a means to explore images and color.
After completing his orchestral work La Mer, Debussy returned to the piano with Images Book 1. His fresh, orchestral perspective gleaned from the massive symphonic work guided his hand in composing Images, and this piano work showcases his creative and unique compositional style. Each individual movement uses subtlety in melody, harmony, and rhythm to create an expressive sound world."(pianistmusings.com)
