It depends on how you research.

If you are studying the physical properties of music, for example, you need to use scientific instruments to measure and record music data, analyze these data, etc. Of course it's science. Here, the research methods must meet the conditions of scientific research.

If you are studying music melody, rhythm, timbre, etc. to make the music better and more moving, then it may be better classified as art. But broadly speaking, music and science themselves are inseparable.
