Here in the UK, it's usual for teachers to advertise in the local free advertiser newspaper that comes out once a week. A small advert in the music classifieds usually does the trick. Also, I listed myself on several piano teacher websites and was amazed at the response. Once you have a few students for a while usually word of mouth takes over from there
All great ideas!! I had the exact same question. Any input on what the going rate is for lessons in the U.S.? I'm afraid that my costs are too cheap. I don't know, please let me know if you think this is absolutley wrong. 30 minute session-$1060 minute session-$20
