Flute is the main treble melody instrument in modern orchestral music and chamber music, belonging to woodwind music. The shape is a long cylindrical tube with several sound holes. Early flutes were made of ebony or coconut. There are many metals used now, such as common nickel-silver alloy or professional silver alloy, 9K and 14K gold, precious metal platinum. Occasionally, performers will use special plastic steel flutes. The timbre of traditional wooden flute is characterized by roundness, warmth, delicacy and low volume, while the timbre of metal flute is brighter and wider. Choose flutes of different materials according to the preferences of the players. However, it is necessary to use a flute uniformly in the band to get the most harmonious and full sound effect. Among western musical instruments, flute belongs to woodwind (woodwind). The pronunciation principle of flute is more special than other musical instruments. It is excited by the continuous positive and negative pressure changes at the air outlet, so the curvature of the air inlet has a considerable influence on the angle between the inner edges of the air outlet, just like the wind blowing thin lines and thick lines. The smaller the included angle, the easier it is to bounce, and the more high frequencies there are. The greater the included angle, the harder it is to play, and the more low frequencies, which also affects the timbre effect of three octaves. The smaller the included angle is, the brighter the timbre will be, while the bass will feel less dynamic because of the low frequency, and the treble will easily be blown out of control into overtones or sharper or finer timbre. If the angle is large, the timbre will feel dull and the bass sound quality will be rich, but it is also easy to feel that the sound will not open.
