What instruments are suitable for primary school music classes?

Instrumental music into the classroom is one of the important contents of music teaching reform in primary and secondary schools. In my opinion, the following conditions must be met: first, there must be a unified musical instrument, which is lifted for the convenience of collective performance; The second is to be cheap and economical; The third is to have good sound quality, which can arouse students' interest; Fourth, the technical requirements are not high, and it is easy to learn. Clarinet, harmonica and organ are the least expensive and easy to carry. It is an introductory instrument for learning music. Unlike bamboo flute, most primary school students can't play it and need a flute membrane. It is easy for primary school students to master the clarinet. As long as the teacher teaches well, primary school students will soon master it and will certainly stimulate their interest in learning music. Harmonica is also small and easy to carry. The disadvantage is that the sound hole is not intuitive, and the scales in the bass and treble areas are not arranged in order. It is also difficult for students to remember how to play and absorb sound. However, as long as they work hard, it is really a good tool. It is not only beautiful in timbre, but also a harmonic instrument, which can be solo, accompanied and ensemble, and is suitable for students of all grades. Of these three instruments, I think the organ is the best. This is a keyboard instrument. Keyboard is conducive to learning the basic knowledge of music. This kind of organ has a loud volume and beautiful timbre. It can play two tones, chord and tone sandhi. After learning the organ, it is very convenient to learn piano, electronic organ, organ and accordion. The organ has 13 key, 24 key and 32 key, among which 13 key organ can't be tuned without black keys, so beginners in lower grades can choose.
