Flute is a high-pitched instrument in the woodwind group of the orchestra, with beautiful timbre, wide range, diverse playing methods and rich expressive force, and strong affinity with string, woodwind and brass instruments. Generally speaking, symphony orchestras should use at least three piccolo, and the third piccolo and alto flute are used for larger bands. As a solo instrument, flute can be played without accompaniment, such as J.S. Bach's sonata in A minor. There are also many solos and concertos accompanied by piano, harp, guitar or band. In chamber music, flute, oboe, clarinet and bassoon become wind quartet; Add a trumpet to form a wind quintet. There are also various combinations. For example, W.A. Mozart wrote three flute quartets, which replaced 1 violin with flutes and consisted of small, medium and cello. There are also many flute combinations in this family. In modern works, piccolo, high, medium and low flutes are combined with flute quintets, sextets and decathlons.

Great composers of all ages have created clarinet works, such as Bach's six sonatas, three Brandenburg concertos and suite in B minor. L.van Beethoven's sonata in b major; Mozart's three concertos; A. Vivaldi's 13 concertos; G.P. Teleman's 12 fantasy; Seven sonatas by g.f. del; Haydn's concerto and three sonatas. Later, the flute appeared and began to slowly replace the clarinet.

Note: Don't think that this clarinet can only be used as a teaching instrument. In fact, the straight flute is an important solo instrument in the history of European music. Straight flute has a long history, and the longest preserved straight flute was made in14th century. There are similar flutes in older western paintings, but when they first appeared has not been determined. Throughout the Baroque era, the straight flute was usually given a solo status similar to a violin because of its perfect timbre and profound skills. Any important composer in Baroque period wrote countless sonatas and concertos for flute. Bach, Gandel, Teleman and Vivaldi are the most famous. Bach is particularly fond of this instrument. In his Brandenburg concerto, he used the straight flute more than the horizontal flute. Especially the second movement of the second Brandenburg Concerto, his three fugues for flute, oboe and violin are classics.

After the classical period, because the flute surpassed the straight flute in volume, this instrument was eliminated by the modern symphony orchestra. Then it was gradually forgotten, and its fate was similar to that of the ancient cello viola da gamba, and it was no longer used as an instrument of standard classical music. Until the 20th century, after entering the modern era, with the rise of retro style, the straight flute regained people's favor. Many contemporary composers have rewritten solos, sonatas and concertos for the flute. In any European country, the straight flute is a regular major in the Conservatory of Music, with the same status as violin and oboe. Flute major does not belong to the orchestra department, but generally belongs to the baroque music department. But its musical charm is obviously not limited to baroque music. Modern excellent flute players can play tartini's "The Devil's Tremble" or many other famous violin technical works perfectly and completely with an 8-hole flute. )

The flute repertoire of China composers mainly includes Meditation by He Luting, Piccolo by Shepherd, Sonata in the Morning by Tian Paul and Sunshine on Tianshan Mountain by Huang Huwei.
