Music performance is a recreation of music. Through the performance of musical instruments, the singing of human voices and various artistic means including conducting, music can be expressed with concrete and sensible voices, conveyed to the audience, and its social functions can be brought into play. It is an intermediary between music creation and music appreciation, and an indispensable link in music activities. Conductor, performer, singer, etc. Through his own artistic practice, he makes different interpretations and performances of music, thus giving the audience different influences and feelings. The re-creation of music. Through the performance of musical instruments, the singing of human voices and various artistic means including conducting, music can be expressed with concrete and sensible voices, conveyed to the audience, and its social functions can be brought into play. It is an intermediary between music creation and music appreciation, and an indispensable link in music activities. Conductor, performer, singer, etc. Through his own artistic practice, he makes different interpretations and performances of music, thus giving the audience different influences and feelings. Therefore, music performance is also a re-creation activity of music. From a historical point of view, music performance is closely related to the development of music art. Although there are complex social reasons, the emergence and gradual diversification of various genres and styles are closely related to the means of music performance and the performance methods adopted. Today, the basic classification of common music genres, such as vocal music, instrumental music and dramatic music, is based on different means of expression. The naming of some schools is also related to the performance form, such as chamber music, chorus, Quyi music and so on. Music performance is more closely related to creation. At first, performance and composition were combined into one. Improvisation and improvisation are the characteristics of folk music and the creative means of professional musicians. These traditions are still maintained among some ethnic groups in the east. In the west, notation has remained in this state for a long time after its appearance. After the Renaissance, the division of labor between professional composers and professional performers gradually appeared. Until the19th century, many composers were still excellent performers (including soloists and conductors). Since the 20th century, this situation has decreased, but musicians who have made remarkable achievements in both creation and performance are still not uncommon. Music performance and creation complement each other. In the process of creation, composers adjust and affirm their musical ideas by playing. The composer's pursuit of musical expression ability promotes the progress of performing arts; The development of playing skills also enriches the expressive means of creation. Through the performance, we can test the social effect of the work from the audience's reaction. For the audience, playing is not only a necessary means to appreciate and understand the content and form of music, but also to appreciate, identify and understand some aspects of music that are emphasized by performers' different interpretations of music. At the same time, the improvement of different playing styles, genres and playing skills has promoted the audience's appreciation and understanding of music. Because of the different performance means used, the requirements for editing this paragraph are different for the performing artists. For example, the requirements for the conductor should include the ability to organize and stimulate the emotions of the band members, while the piano accompanist should be good at setting off soloists or giving full play to the characteristics of soloists. But from a big perspective, it is nothing more than two aspects: first, it has rich artistic accomplishment and can master the different characteristics and specific expressions of music in various historical periods; The second is to master higher playing skills, which can make the skills come out freely and freely. For specific works, we should not reproduce the notes on the score mechanically, but should reflect the rich connotation of music, which has both the style of the times and personal characteristics. If a group of performing artists have similar understanding of music works, similar expression techniques and performance styles, and have formed relatively stable performance traditions and their own characteristics due to historical or social reasons, it can be said that a certain performance genre has been formed. Various ethnic groups have formed many musical performance schools in different periods, and the characteristics of each school are often passed on to future generations through music education, which makes music culture present colorful characteristics. In the west, piano, violin and vocal music are more prominent in instrumental music. In China, the traditional opera singing schools such as Guqin and Pipa in national instrumental music have their own characteristics. In recent years, vocal music singing schools have gradually formed. Editing the performance theory of this paragraph, I have explored the music performance theory in many aspects, including the special research on the performance style, specific musical instruments and vocal music technology in various periods, which are scattered in many documents. In China, there are many ancient records about performing music performances. It is particularly worth mentioning the operas and guqin performances after the Yuan Dynasty, such as On Singing by Zhi 'an in the Yuan Dynasty, Qin in the Mountain by Xu Shangying in the Ming Dynasty, Yuefu Biography by Xu Dachun in the Qing Dynasty and Qin Xue Essence by Jiang Wenxun. Since the 20th century, the famous western theoretical works on the general theory of performing arts and the general history of music performance include: History of Music Performance by Haas, History of Music Performance by Dorian, Music Interpretation by Dart and Music Interpretation by Westrup. Some aspects; At the same time, the improvement of different playing styles, genres and playing skills has promoted the audience's appreciation and understanding of music. Music education refers to high-tech applied talents who are familiar with the basic theory, performance, basic teaching skills and artistic practice knowledge of music performance. Strong vocal and instrumental performance ability and music appreciation and identification ability, master the analysis method of music works, and have certain music creation ability; Strong ability to organize music education and teaching activities, literary and artistic activities and competitions; Have certain ability of music education and scientific research.
