The flute is a wind instrument, a reedless woodwind instrument that produces sound by air passing through the opening of the instrument. According to the Hornbostel-Saxophone classification, the flute is an edge-blown aerophone.

The common flute is a straight long tube.sexdoll In addition to the mouthpiece for playing, there are several openings for adjusting the pitch. The opening or closing of each opening will produce different pitches. There are different flutes in different places. Some flutes (such as recorders) are recorders with the mouthpiece at the end of the flute. When playing, the flute is perpendicular to the lips. Some flutes (such as flutes) are horizontal flutes, with the mouthpiece on the side of the flute, and the flute is parallel to the lips when played.

The flute is the oldest musical instrument besides the human voice. In archaeological research, the earliest flute was discovered in Slovenia 43,000 years ago. It was made by sawing off the femur of a young cave bear and drilling holes into the joints at both ends. flute, but this discovery is still controversial[1][2]. Many Paleolithic flutes were discovered in Swabian Albi, Germany, dating from about 43,000 to 35,000 years ago.love doll From these flutes, it can be seen that humans in Europe had a tradition of playing musical instruments at that time [3][4]. In China, a Jiahu bone flute dating from about 9,000 to 7,700 years ago has also been discovered.

The pronunciation method of the flute is to use the air flow directly through the opening of the flute, and the air vibrates at the opening to produce sound.

The air passing through the opening is siphoned according to Bernoulli's law, thus vibrating the air inside the flute.Silikonsexpuppen The player closes the opening at a specific location to change the length and resonance frequency of the resonant tube in the flute, thereby adjusting the pitch of the flute. The player can also adjust the air pressure of the flute without adjusting the opening, so that the resonance of the flute moves from the fundamental frequency to a certain harmonic, so the pitch can also be adjusted.

The geometric shape of the mouthpiece is particularly important to the sound performance of the flute. As for which shape is the best, there is no consensus among the instrument manufacturers. The acoustic impedance of the blowhole is the most critical parameter of the flute. The main influencing factors are: chimney length (the space between the lip and head tube), chimney diameter, radius at the end of the chimney, curvature,MILF Sexpuppen or holes in the instrument that specifically restrict air flow.

The simplest flute is a pipe with an opening, and there are many types of flutes. When playing most flutes, the player covers the mouthpiece of the wind instrument with a quarter of his lower lip. However, flute instruments such as whistles, recorders, tin whistles, tonettes, and ocarinas have a tube that guides air, called a whistle. These flutes are called "whistle flutes."Riesige Brüste Sexpuppen The design of the whistle makes this type of instrument simpler and easier to play than flutes without a whistle.
