What is the difference between symphonies and symphonies?

symphonic poem, a kind of one-movement title symphony music, was born out of the concert overture in the 19th century (185), emphasizing poetic and philosophical expression. Symphonic poems are not unique in form, and they are often played freely according to the principle of sonata form. Symphonic poem is a kind of free-form single movement title symphony music, and its predecessor is concert overture. Symphonic poetry embodies a philosophical thought, a poetic mood or a certain literary theme in conception. Symphonic poetry was founded in the mid-19th century by Hungarian composer Liszt. The name of the symphonic poem was created by F. Liszt. He thought that "the title can endow instrumental music with all kinds of subtle colors, which are almost the same as those expressed by different poetic forms" (Berlioz and his Harold Symphony), so he linked the title symphonic music with the poem and called it symphonic poem. His thirteen symphonic poems take poetry, drama, painting and historical deeds as themes, and widely use the method of theme deformation to shape the artistic image of specific titles. Symphony is a genre of instrumental music, and it is a large-scale (sonata-type) suite with multiple movements played by an orchestra. Originated from the overture of Italian opera, Hai suddenly took shape. The basic features are: Allegro in the first movement, in sonata form; The second movement is slow, adopting a two-part or three-part form, etc. The third movement is moderate or slightly faster, and it is a minuet or scherzo; The fourth movement, also known as the "final movement", is rapid and adopts Rondo sonata form. The word "Symphony" originated in ancient Greece, and its original meaning was "ringing". To the Middle Ages, it refers to the harmonious combination of two tones, and sometimes it also refers to an Italian composer G, who first used it as the title of the song, and called the sacred music of his vocal music and instrumental music "Sacred Symphony" (1597). Since then, it generally refers to the music performed by vocal music and instrumental music. In 167, A, Bankina and S Rossi each published a symphony of pure instrumental music. In 1619, m. In a book on modern musical forms, Praetorius proposed that symphonies should be purely instrumental works without any vocal parts. From then on, the symphony began to get rid of vocal music and turned into instrumental works, marking an important turning point of the symphony. Since then, many instrumental works, such as operas, oratorios and other instrumental introductions, overtures or preludes; J. Bach's three creative songs and Partita's opening movement; Some quartets of J. Haydn are collectively called symphonies. In the 2th century, I.F. Stravinsky deliberately archaized and wrote the Symphony for Wind Instruments (192).
