If you want to be teaching music at a stage where you need a degree. That is very straight forward. This does not refer to stuff like teaching piano in your home to children, more like teaching music in some kind of school.River Ridge School of Music & Dance
You are a classical singer, and not the man who was already signed to record deals as a prodigy of 14 years. In schools like Julliard and Peabody, a lot of people are developing their skills in search of the goal of hearing for anything (like an orchestra). Remember- for them the endpoint is not the degree, it is the audition. Note: You may need to work out ways to supplement your income at some stage if you are in this community, and reason # 1 (capacity to teach) may be helpful.
Learning different skills which are difficult to learn from other sources. There are some amazing schools that also concentrate on the modern music world of today (think of Berklee and Oberlin), as opposed to the more conventional schools. Learning skills such as music composition will bring you miles ahead of the throngs of people at home using apps such as Garage Band.
Music school also teaches some very valuable life skills (I am serious), and medicine-to-law degree programs look at music school majors who have been serious about their craft as people who know commitment and time management. This is incredible but real. Trust me, I know firsthand about this one. You also need to have all the criteria for the area you quit for professional music, but your background music makes you viewed as “unique and well-rounded.”
My most important reason for going to music school, and a general reason for choosing music as a career: because you can’t picture yourself able to do anything but music. A music career is hard — many people who are in music for a living have to put up with lots of parts that they don’t really like, just to get to the tiny bits that they live for. It can be hard and you are joining music for the wrong reasons if your only goal is to be rich and famous.
So ask yourself, why do you want to go to the school for music? If you just can’t imagine being satisfied doing something other than music, you think they can give you the practical skills you need, you need the organized practice setting, plus you’ve got the patience and commitment (and funds), then maybe music school is right for you.
