How to practice keyboard improvisation accompaniment

Impromptu accompaniment consists of the following elements: piano skills; Harmony Foundation; Type of accompaniment sound; Song analysis; Comprehensive application ability. 1. Piano Skills One of the necessary conditions for piano improvisation is piano skills. People who can't play the piano can't play the piano accompaniment. Ammunition is very clear, piano skills are by no means equal to accompaniment skills, and they are essentially different: the former is based on mechanical practice to reproduce music content, while the latter is creative labor to complete the task of song accompaniment. Make it a whole that complements the song. So there will be the following two situations: First, the level of accompaniment is restricted by piano skills. This kind of person has strong theoretical level, strong creativity and comprehensive application ability. As long as the piano skills are constantly improved, the accompaniment level will rise. Second, the piano skill is higher than the accompaniment level, that is to say, the accompaniment level is restricted by the theoretical level, creativity and comprehensive application ability, which requires systematic and comprehensive study and hard training. Second, the improvisational accompaniment based on harmony belongs to the category of multi-voice, and it needs to have a harmonious foundation. The level of harmony is directly related to the sound effect and expressive force of accompaniment, and there are special courses to study the writing of harmony practice. However, the writing of harmony practice is different from the specific application in impromptu accompaniment. For example, the choice of harmony should be considered according to the needs of specific works, and the level, connection, omission, functionality and color should be handled well. Rhythm, expressive force, chord structure and chord external sound, harmony style and so on. This series of problems have fixed rules in practice, but they are very flexible in practical application. Some problems can't be touched in exercises, but they must be handled well in practical application, so harmony foundation is very important. It is necessary to make a statement in a certain form. Accompaniment sound form is a regular statement form in the basic application of harmony and specific works. Whether this form is suitable or not, and how to choose it properly, should have certain basis, such as piano performance, the characteristics and expressive force of accompaniment, playing methods, the player's existing piano skills and the level of application ability. In addition to the harmony effect, the accompaniment effect is mainly the application of accompaniment sound patterns. Therefore, the creative selection and design of accompaniment sound type is an indispensable and important content in playing impromptu accompaniment. Fourthly, the analysis of the genre, form, form and content of songs is the basis for correctly choosing the forms of harmony and accompaniment. As far as harmony is concerned, the definition of mode, the determination of semi-termination and termination, the chord structure, the harmony effect and the style are all consistent with the content of the song. Children's solo and mixed chorus will also have differences in sound type, sound level, strength and playing method; That is, the same song, from presentation to climax reproduction, can not be treated in the same way. Therefore, it is very necessary to analyze songs from the needs of accompaniment, especially the choice and application of accompaniment mode. Fifth, comprehensive application ability refers to the integration of piano skills, harmony foundation, accompaniment form and song analysis, as well as improvisation and cooperation with singers. Artistic practical experience, etc. The cultivation and exercise of this ability is the key to play impromptu accompaniment well. In addition to the above elements, we should continue to study, improve, cultivate and exercise in the following aspects, that is, rich imagination and creativity; Flexible adaptability; Diligent and diligent learning spirit; Proficient in piano playing and keyboard timbre; Further study professional theories (polyphony, orchestration), constantly sum up and accumulate experience in practice, find something and create something.
