If you decide teaching is for you, then proceed to earn M.Ed & do student teaching to qualify as a music teacher.
Otherwise, if you hold a performance degree, audition for orchestras, bands, groups, whatever. If your degree is more musicology, music history, music theory, AND, for example, you are a superior writer & critic, see if you can place some freelance reviews, work your way up to reviewer.
What do you WANT to do? What are your strengths, talents, interests, etc? It's totally up to you to decide what you want, and go after it, proving you have the qualifications to do an excellent job at that.
