Overview

• Harmonica, a multi-reed instrument that uses the mouth to blow or inhale to make the metal reeds vibrate and produce sound; it is a free-reed wind instrument in the classification of musical instruments. Since the sound source is a reed with a length between 1.5-3.5 cm rather than an air column (such as a flute), the volume of the solo harmonica is usually within 20×6×4 cm (length; width; height). Its range depends on the type and key.Silikonsexpuppen There are slight differences depending on the gender. It can be roughly summarized from 1 octave below middle C to 3 octaves above middle C, covering about 3 to 4 octaves.

  The multi-reed structure gives the harmonica the foundation for playing harmony. For ordinary adults, as long as the reeds are arranged in the same direction (either by blowing or inhaling) and the grid spacing is within 6 centimeters, they can all sound at the same time; because the reeds on the same harmonica cannot be adjusted during the performance, Relative to the position, the ability of a single harmonica to play chorus is limited.Mollige Sexpuppen Generally speaking, harmonicas mass-produced by musical instrument companies are less restricted only in terms of octave harmonies.

  There are different opinions on its origin. It is said that the sheng was introduced to Europe in the 18th century, providing musical instrument designers with the theoretical basis for free-reed wind instruments. The earliest known prototype of the harmonica was made by Friedrich Buschmann in Berlin in 1821.Schlanke Sexpuppen

  The basic structure of the harmonica is the reed, seat plate, fret and cover.

  The reed is fixed on the seat plate. Generally, harmonicas produced by harmonica factories use rivets or spot welding to fix the reed. For the convenience of maintenance, some people process the seat plate and modify it to use screws to fix the reed.

  In addition to the reeds, seat plate, fret and cover, the chromatic harmonica also has a mouthpiece, spring and key slider.Anime sexpuppen There is a plastic sheet stuck to the seat plate, which can effectively reduce the air circulation in the gap between the non-sounding reeds during performance and increase the air density.

  The common ten-hole harmonica does not have film attached, but in order to meet the performance requirements of single-reed compression, there are also designs where film is only attached to the treble reed in the same air chamber (fret position). This design of sticking film on the ten-hole harmonica is called half-valving, and was invented by New Zealand harmonica player and modifier Brendan Bower.große brüste sexpuppen
