If you're a high school junior, now is the time when you're probably starting to think seriously about what you want to do after graduation. If you're interested in studying music at the college level, it can be hard to tell how you compare to your competition and if you have what it takes to get into a good music program.
Here are some things you should consider if you're thinking about studying music:
Am I prepared to be tenacious?
Depending on your background and the major you choose, there will be things about your curriculum that you find difficult to the point of impossibility. Many people change majors when they come up against these challenges, but the ones who bite down and refuse to give up are the ones who end up with their music degree.
Am I willing to be resourceful?
There will be times when you aren't sure what's going on in a class. Be willing to seek help if you need it, whether from a fellow student or your professor. A lot of professors spend their office hours sitting and waiting for a student to care enough to come ask for assistance with something.
There will also be times when music school gets incredibly stressful. Most schools offer some sort of counseling or mentorship program, and you should take advantage of this resource if things start to feel overwhelming.
Do I have any idea what I want to do within the music field?
It's not enough to love music and want to spend four years at band camp. You need some idea of what you want to pursue, even if you don't have it completely narrowed down yet. Common fields of focus include education, performance, musicology (history and analysis), music theory, and composition.
Am I aware of my financial future?
Unless you're independently wealthy, chances are you'll need to take out some student loans to cover the cost of music school. Bear in mind that music is not a traditionally high-earning field; for every big-name orchestra musician who makes six figures a year, there are many, many musicians piecing together a career that supports them financially and spiritually but doesn't leave a ton of financial wiggle room.
Am I looking for a 9-5 job?
Because if you are, music is not the field for you. Performers tend to work evenings and weekends, and teachers work all day and into the night. If you want a desk job with guaranteed vacation time and benefits, music is not the field you should choose.
So perhaps the question shouldn't be "Am I good enough to go to conservatory," but rather, "Is conservatory something I want?"
Do some serious thinking about what you want out of it and how it will benefit you to go to music school. If you're unsure, examine why, and be honest with yourself about whether it's the right decision. But if at the end of your introspection you determine that music is a non-negotiable part of you, a part that would diminish and cripple you if it were taken away, then you'll love conservatory. Go for it.
