With the more and more deep understanding of the importance of education, the innovation of education in China is also actively carried out. Learning the course of music theory is as if learning pinyin before language, and if students do not know the basic music theory, they are bound to have a lot of difficulties in the later learning process, thereby losing confidence and interest in music. The students who have learned the music theory course can learn music integrally and systematically, and can associate the knowledge learned by the students when learning the music, so that the students can learn more comfortably, the confidence of the students can be enhanced, and the interest is improved. Piano education is an important component in music education, and art culture and literature culture of students are of great significance and are an important component in student education.
When learning a piano, problems such as intonation, rhythm, and musicality of students are due in large part to lack of mastery of basic knowledge and skills of music. In the course of teaching, teachers are difficult to give important teaching to certain students, and students are difficult to learn weak points in class. Therefore, post-session exercises become an important period for students to break through weaknesses. However, in the actual post-session practice, the students cannot deeply practice weak points because the students do not completely memorize and digest the teaching contents of teachers, so that the post-session practice efficiency is not high.
