Rhythm is an essential element in musical composition, and in musical language, rhythm is like a skeleton. Music without rhythm will become a chaotic list of notes, let alone shape the image of music. Therefore, in playing, it is very important to master the rhythm, which directly affects the performance of art. Hulusi sight reading and notation are equally important!
Look at the rhythm first, then the melody. Card the rhythm, and then fill in the corresponding notes. The reason why many people don't know notation is that the rhythm is not good, the music cannot be completed, and the problem of intonation is easy to solve. Practice more scales, and sing more songs that you are familiar with, and gradually the pitch will come up. Some symbols on the musical score are memorized by rote. Although the method is stupid, it is a good way to solve the problem.
It would be a pity if an aficionado has a certain foundation in the playing of cucurbit flute, but does not know notation or the necessary knowledge of music theory, which affects the development of his playing level. Therefore, it is necessary to have a certain basic knowledge of music theory!
