Some Problems In The Configuration Of Electroacoustic Bands And The Application Of Musical Instruments

Among the four instruments of the electroacoustic band,except for the drum kit that have no pitch,the remaining three instruments form exactly three parts,namely the high part(electric guitar),the middle part(keyboard),and the low part(Electric bass).The stereo contour of an electroacoustic band can be basically reflected in these three parts.In recent years,the number of electro-acoustic bands in China has also grown particularly fast.It can be said that they are one after another.Their performances are very good in these bands,and each has its own characteristics,but in contrast,They lack theoretical research on the technical problems of the orchestration and have obvious technical theoretical problems.The problem that frequently occurs with electroacoustic bands is " synchronous of rhythm",the worst of which is the rhythm synchronization that occurs in intensive rhythms.The soul of one band is electric guitar,It can't be replaced by all other instruments.The electric guitar can not only appear in the high-pitched area in the form of rasgueado,but also in the akkrode of soothing music melody.And more importantly,it can perform at the beginning,middle,or end of one song melody.The synthesizer in the electroacoustic band,we call it the basis of the band.It can combine the sounds of the all instruments in the band to form a rigidity softness,a unified effect.It also is a joiner in the band.In the performance process,abundant chords of synthesizer can enrich the middle part of the song melody and can make up for the shortcomings in the band performance.It also can provide a soft music background in the melody and perform the deputy melody in the super high part.As the foundation of the band,the electric bass is the low voice of the band.An electroacoustic band without electric bass is very unharmonious.The main function of the electric bass is highlighted in the rhythm of the low voice.The effect is well than other instruments if it is used playing the melody.The drum kit bear the skeleton of the rhythm of the band.The rhythm of the drum kit can determine the basic style of a band's rhythm.The other instruments can play their own performances with reference to the rhythm style of the drum kit.The drummers need to have agood rhythm sensation,speed,strength,memorization and mastery.Furthermore drummers also have their own unique design capabilities and control over the entire team.In short,in the band,the drum is a commander.After understanding the above,we must first determine the rhythm,followed by the cooperation between the electric guitar and the keyboard.In addition,we must determine the contrast method and the effect of the front,the middle,and the ending when we are in the orchestration.The final question is the form of the electroacoustic band,which is somewhat different from the orchestra notation and has its own regularity.
