The admonition to teachers to avoid solicitation of students from another studio originates I think in the competitive nature of many events that music students and their teachers participate in. The professional aspect of teaching music should not center on getting the best students in order to win competitions, and the discouragement of soliciting students for competitive purposes resonates as ethical with the majority of teachers. I seriously doubt that very many teachers would solicit a student away from another studio by offering a lower lesson fee. The issue is usually offering a competitive edge or more prestige in the competing studio. A teacher may work with a talented student for years and when that student progresses to the point where they are receiving competitive recognition, teachers resent a better-known teacher approaching the student about changing studios. Most professional teachers know when they cannot offer an advancing student the instruction that he needs, and will propose to the student that he seek out a different teacher. The practice of "robbing" a student is viewed as unethical by most music professionals.
