Where in Cincinnati can I take music lessons?

If you don't wish to go the college route, a company called Musika: http://www.musikalessons.com/violinteacherscincinnati.htm is a referral service for private lessons on a number of instruments. They offer teachers across the country, including Cincinnati.

I will always recommend CCM for any sort of music lessons. Since it's one of the highest-ranking performing arts schools (ranked 6th nationally), it's hard to go wrong. I grew up taking piano lessons from professors at CCM, for example, and they were always both very professional and very talented. If you take lessons through one of the music programs, you also have access to their facilities, which are very high-tech and a great asset to any musician's career.
