Musical sounds are sounds produced out of singing or music-instrumental display that is in no way referred to as noise.
The first seven letters of the alphabet (A B C D E F G) best explain musical sounds.
Musical symbols are the marks and symbols, used since about the 13th century in the musical notation of musical scores, styles, and instruments, in order to describe pitch, rhythm, tempo – and, to some degree, its articulation (e.g. a composition in its fundamentals)… Music notes are written on the stave. The stave consist of five lines and four spaces, which run parallel across the page. In addition, the piano is one of the best instruments that can be used to explain music better.
