Finish your music performance degree. Perhaps the best thing to do is take some time after undergrad. Get a job. Maybe teach private lessons. Continue to play in some kind of ensembles while also exploring other options.
Music majors do all sorts of things. The music majors we know have became certified financial planners, bookkeepers, nurses, lawyers, college instructors, work in music administration, public school educators, members of military ensembles, composers. These are real people we know.
Having a degree in music shows an incredible amount of discipline and dedication.
And don’t give up! Do some auditions for some ensembles. Ask your private teacher for suggestions…they will have some. You need to keep your ears to the ground for these auditions.
