Neoclassicism in music was a twentieth-century trend, particularly current in the interwar period, in which composers sought to return to aesthetic precepts associated with the broadly defined concept of "classicism", namely order, balance, clarity, economy, and emotional restraint. As such, neoclassicism was a reaction against the unrestrained emotionalism and perceived formlessness of late Romanticism, as well as a "call to order" after the experimental ferment of the first two decades of the twentieth century. The neoclassical impulse found its expression in such features as the use of pared-down performing forces, an emphasis on rhythm and on contrapuntal texture, an updated or expanded tonal harmony, and a concentration on absolute music as opposed to Romantic program music. In form and thematic technique, neoclassical music often drew inspiration from music of the 18th century, though the inspiring canon belonged as frequently to the Baroque and even earlier periods as to the Classical period—for this reason, music which draws inspiration specifically from the Baroque is sometimes termed neo-Baroque music. Neoclassicism had two distinct national lines of development, French (proceeding partly from the influence of Erik Satie and represented by Igor Stravinsky, who was in fact Russian-born) and German (proceeding from the "New Objectivity" of Ferruccio Busoni, who was actually Italian, and represented by Paul Hindemith). Neoclassicism was an aesthetic trend rather than an organized movement; even many composers not usually thought of as "neoclassicists" absorbed elements of the style. People and works Although the term "neoclassicism" refers to a 20th-century movement, there were important 19th-century precursors. In pieces such as Franz Liszt's À la Chapelle Sixtine (1862), Edvard Grieg's Holberg Suite (1884), Pyotr Ilyich Tchaikovsky's divertissement from The Queen of Spades (1890), George Enescu's Piano Suite in the Old Style (1897) and Max Reger's Concerto in the Old Style (1912), composers "dressed up their music in old clothes in order to create a smiling or pensive evocation of the past". Sergei Prokofiev's Symphony No. 1 (1917) is sometimes cited as a precursor of neoclassicism. Prokofiev himself thought that his composition was a "passing phase" whereas Stravinsky's neoclassicism was by the 1920s "becoming the basic line of his music". Richard Strauss also introduced neoclassical elements into his music, most notably in his orchestral suite Le bourgeois gentilhomme Op. 60, written in an early version in 1911 and its final version in 1917. Ottorino Respighi was also one of the precursors of neoclassicism with his
