For a class project, I need to ask a bunch of brass instrument manufacturers to send me information about their instruments so that I will be able to use the info as a resource when I am a teacher. However, I'm having difficulty finding enough manufacturers because we are only allowed to have one major distributer, but many companies (bach, besson, con-selmer, king etc) have been bought out by larger companies/distributers. I would really appreciate if you list all the companies that you know of, if you know of any. Thanks so much!
