While in Illinois, a number of students were referred to me from harp dealers. I also put up a lot of posters and played some concerts, but I’m not certain how many students came from those sources. I also taught harp at a couple local colleges which helped.
I just moved to Minnesota and got my first harp student here through a local music store and may work through a second store. I have sent out resume’s and emails, but if you don’t meet in person, I suspect materials get thrown away and deleted. Referrals are the most effective way to get employment at a college or community music school which is a great target audience for students. Oftentimes the people who attend performances are more interested in buying a CD than learning the instrument, but the people who are buying instruments, or happen to have a harp, are the ones who are most likely to invest in lessons. Basically, harp dealers and well known institutions that offer music lessons are the most direct route to obtaining students, in my experience.
