The word "Music" is not really used to describe "ноты", which means "notes" or "scores". I am not saying to call it music is incorrect, but "scores" is probably used more often.

"Партитура" on the other hand is another correct answer, everything depends on the context. If you are talking about something that the musician reads from paper - that will be "партитура" .
