Hard to say. I think you would have to ask people like Dapogny, Scivales and Posnak. I suspect not, because much music is digitised at the point of creation these days, which process renders transcribing unnecessary. If you have a good ear it is a handy process to develop at the personal level but I think you would have to be abnormally quick and accurate at it to make money from it.I do not immediately see why courses in composition would help this ability.
>>allchopin<< Thanks for your encouraging words. I suspect that offering transcriptions as a service in addition to other means of making money would provide enough income. I'm just trying to find something that I'll really enjoy doing. You mention "being able to hear progressions rather than individual notes," and I suspect this is my biggest weakness. Hopefully college will provide the resources to address that problem.
