New York is an incredibly difficult place to do it. Everyone is interested in the “money” instruments that famous people play. I never saw a city with fewer harp students per capita. There should be thousands, but there are not. It depends on what area you are in. I don’t know what works, because nothing seems to work except being in directories and having a good background. If you can figure out something to do that will get you to be well-known, at least locally, that might help. People seem to get quite stupid when they decide to look for a harp teacher, they never know where to look. It also might help if you can open some kind of harp store.
