I don’t usually do this, but I thought I’d share a link with you all. I found a very interesting article on music-oriented jobs. The musicians I know typically have multiple music jobs (e.g. the school music teacher who also is a church music director, the orchestra player who also operates a private lesson studio, etc.). Music careers are appreciated for their flexibility. You can mix and match different jobs so that you can cater to your strengths and time commitments. It can be frustrating if you are looking for stability. Think of yourself as more of an independent contractor, and you will do fine.
Look through the following careers and see what interests you. Maybe it will give you some ideas on how to make more income.
