How to make a musical instrument page on Facebook?

[INoKnow1]

The category you attach a page to on Facebook doesn't really matter.

You have two options. You can choose either 'Local Business" or "Brand or Product".

Under "Local Business" you can simply call yourself a "Professional service". Under "Product" you can call yourself a "Product/Service".

It depends on which of those two options you consider what you do to be most similar to. But, as I said, the category makes no difference. It's the appropriate nature of the name of the page and it's content that will attract people it it.
