Sound principle of percussion instruments

Percussion is an instrument group that produces effects by knocking, shaking, rubbing and scraping. So, what are the principles in the process of percussion? Let me tell you about the sound principle of percussion instruments!

A brief analysis of the sounding principle of percussion instruments: drums, gongs and other instruments will vibrate and make sounds when they are struck. Take the drum as an example. The tighter the drum head, the faster the vibration and the higher the tone. The greater the strength of the drum, the greater the vibration amplitude and sound of the drum skin.

Introduction to percussion instruments is also called percussion instruments? Percussion instrument? , refers to the sound made by the percussion instrument itself. Some are percussion instruments with fixed pitch, such as cymbals and chimes. There are also some percussion instruments that have no fixed pitch, such as bangzi, bangzi, banjo, waist drum and tambourine. According to the different pronunciation styles of percussion instruments, they can be divided into two categories: (1)? Ge Ming musical instrument? Also called? Membrane musical instrument? , that is, an instrument that beats the leather membrane or the leather membrane on the instrument, such as various drum instruments; (2)? Body singing instrument? By striking the body of musical instruments, such as chimes, wooden fish, gongs, cymbals and bells.

Most percussion instruments have a clear sound, even the sound of drums is clear. But generally speaking, the classification of percussion instruments is to see whether an instrument has a certain pitch.

Timpani, xylophone, marimba, vibrato, bell, pipe bell, cymbal and Zhong Qin all have a certain pitch. Drums, drums, sand hammers, castanets, sounding sticks, cowbells, hanging cymbals, sand balls, gear vibrators, spoons, wooden fish, drums, bronze drums, triangle irons, vibrators, washboards, whips and nanbangzi generally have no definite pitch. But some percussion players will determine the pitch of their drums before recording records or playing special works. There are two kinds of gongs: those with fixed pitch and those without fixed pitch. Generally speaking, western gongs do not have a certain pitch. Hanging cymbals also have a certain pitch, but rarely.

In addition, percussion instruments are also divided into membrane instruments and self-sounding instruments. Membranous instruments are covered with a membrane, and the membrane of percussion instruments produces sound, such as drums. Spontaneous acoustic instruments can make their own sounds, such as triangles. Tambourine is not only a membrane instrument, but also a self-sounding instrument.

Chinese musical instrument

There are many unique percussion instruments in China's national musical instruments. Some of these percussion instruments are still in use today, and some are no longer in use (such as chimes). Many of these traditional percussion instruments are an indispensable part of China's traditional arts, such as chimes, drums, gongs and cymbals in China's plays, or allegro and castanets for telling stories.

Percussion instruments are rarely used in traditional music in China, and percussion instruments (except xylophone and chime) are generally regarded as subordinate instruments. For example, in the literature of the Spring and Autumn Period and the Warring States Period, there were articles mocking Qin percussion.

Western musical instruments

Timpani is the most widely used, only used to enhance the momentum of music. Then snare drum Jr, Dajun drum, cymbals, xylophone, etc. But then the music gradually diversified, so the rich rhythm of percussion instruments was well used. At the beginning of the 20th century, wind music began to develop, and various percussion instruments were gradually developed and perfected. Composers were able to make use of various acoustic effects to make music more colorful. Then snare drum Jr. and timpani became the key percussion instruments, which could lead the whole band to the direction and beat, equivalent to assistant conductor.
