Impressionism in musicImpressionism in music was a movement among various composers in Western classical music (mainly during the late 19th and early 20th centuries) whose music focuses on mood and atmosphere, "conveying the moods and emotions aroused by the subject rather than a detailed tone‐picture". "Impressionism" is a philosophical and aesthetic term borrowed from late 19th-century French painting after Monet's Impression, Sunrise. Composers were labeled impressionists by analogy to the impressionist painters who use starkly contrasting colors, effect of light on an object, blurry foreground and background, flattening perspective, etc. to make the observer focus his attention on the overall impression.
The most prominent feature in musical impressionism is the use of "color", or in musical terms, timbre, which can be achieved through orchestration, harmonic usage, texture, etc. Other elements of music impressionism also involve new chord combinations, ambiguous tonality, extended harmonies, use of modes and exotic scales, parallel motion, extra-musicality, and evocative titles such as Reflets dans l'eau (Reflections on the water, 1905), Brouillards (Mists, 1913) etc.
Claude Debussy and Maurice Ravel are two leading figures in impressionism, though Debussy rejected this label (in a 1908 letter he wrote "imbeciles call [what I am trying to write in Images] 'impressionism', a term employed with the utmost inaccuracy, especially by art critics who use it as a label to stick on Turner, the finest creator of mystery in the whole of art!") and Ravel displayed discomfort with it, at one point claiming that it could not be adequately applied to music at all. Debussy's impressionist works typically "evoke a mood, feeling, atmosphere, or scene" by creating musical images through characteristic motifs, harmony, exotic scales (e.g., whole-tone and pentatonic scales), instrumental timbre, large unresolved chords (e.g., 9ths, 11ths, 13ths), parallel motion, ambiguous tonality, extreme chromaticism, heavy use of the piano pedals, and other elements. Some impressionist composers, Debussy and Ravel in particular, are also labeled as symbolist composers. One trait shared with both aesthetic trends is "a sense of detached observation: rather than expressing deeply felt emotion or telling a story"; as in symbolist poetry, the normal syntax is usually disrupted and individual images that carry the work's meaning are evoked.
While impressionism only began as a movement after about 1890, Ernest Fanelli was credited with inventing the style in the early 1880s. However, his works were unperformed before 1912. The performance of his works in that year led to claims that he was the father of musical Impressionism. Ravel wrote, "this impressionism is certainly very different from that of present-day composers...Mr. Fanelli's impressionism derives more directly from Berlioz." He added that Fanelli's alleged priority does not in any way diminish the achievements of later composers: "the investigations of the young Fanelli could not have diminished those of his colleagues...It is peculiar that these investigations suddenly assume importance because their embryo is discovered in a work written 30 years ago."
Other composers linked to impressionism include Lili Boulanger, Isaac Albéniz, Frederick Delius, Paul Dukas, Alexander Scriabin, Manuel de Falla, John Alden Carpenter, Ottorino Respighi, Charles Tomlinson Griffes, and Federico Mompou. The Finnish composer Jean Sibelius is also associated with impressionism, and his tone poem The Swan of Tuonela (1893) predates Debussy's Prélude à l'après-midi d'un faune (regarded as a seminal work of musical impressionism) by a year. The American composer Howard Hanson also borrowed from both Sibelius and impressionism generally in works such as his Second Symphony.
