"Sounding" and "playing" are both terms in the field of music, but their meanings are slightly different.

"Singing" usually refers to the act of playing an instrument or singing a musical work, which means that the music can be heard through playing or singing. This word emphasizes the communication of musical works to an audience or listener through a specific way of playing or singing. For example, when a musician plays a piece of music, we can say that he "played the piece."

"Performance" is broader. In addition to playing an instrument or singing a musical work, it can also include other forms of performance, such as performances by stage actors. Different from "playing", "playing" puts more emphasis on the skills and artistry in the entire performance process. Playing requires more skill and practice, and usually requires a lot of practice and training to reach a certain level.

In summary, "playing" emphasizes conveying musical works to the audience or listeners through specific performances or singing methods, while "performance" is broader, including music performances and other forms of performances. .
