You are very welcome. The bachelor’s is a 4 year degree, but if you already have a music degree, it takes a couple years to take the classes required to sit for boards. As far as jobs… it depends on where you are living, and where you want to be in 4 years. Some states’ music therapy associations have done of ton of advocacy, and there will be even better awareness in 4 years. It also depends on how and where you want to work – do you want to hang out your shingle, or do you want to be an employee of a service provider such as a school, social service agency or hospital? These are not questions you have to answer now. You will get a better idea throughout your schooling which direction you want to take.
Also, if you are serious about pursuing this, you should contact a school ASAP. Admissions decisions are being made now, and because of the way the tracks are set up, you usually have to start in the fall.
I’m happy to answer any more questions you may have. Good luck!
