I would suggest you post this query on the music majors section of this forum. There are many folks there with students who majored in music, music education, or some other combination of music majors.
I will give you my opinion…
Many fields require a masters degree now. A bachelors in music performance is not a horrible thing. Some will become performers, and others will work in the music field in some other capacity.
And still others will get advanced degrees in any number of other fields.
