What's the difference?

Both require study, thoughtful preparation, and regular practice to learn the skills necessary for adequate performance.

Shared with appropriate others, even a mediocre performance can be rewarding, and appreciated.

Performed with, or for, someone inappropriate or unappreciative, either can be a total flop.

With either, one can choose whether to be the performer or the recipient participating audience, and the variety of forms, styles, methods, techniques, and instruments available are sufficient for life-long enjoyment of them both.

Neither is - eventually - much fun if you only know "one song" and try to play it the same at every performance.
