Honestly 6-12 students is all anybody can take and be able to do their students justice with their lessons. I wouldn't ever take lessons (on a regular basis anyway) from someone with more students than that, because then you're just a face in the crowd. Although I shouldn't say never, because it lso depends on who the teacher is.For me, there have been times when I've been hurting for students, and other times when I've had to turn people away because I just can't fit them in. And I haven't even been teaching for that long (a little less than two years), so that may give you an idea of how quickly things can change. Give it time. A private teacher usually needs to develope a local reputation in order to keep more regular students and keep new students coming in.Don't be discouraged, because lots of kids start piano and quit within a short time. It's not your fault as a teacher, it's just the short attention span of kids. For most kids, piano is just a phase they go through and they get bored with it. Only a relative few stick with it for the long haul. And sometimes it's the parents who can't or don't want to shell out money for lessons.Also, I don't know what your performance situation is, but it helps to be a presence in the community. One student I have now saw me play a concert with my jazz trio, and I ended up talking to him afterwards. He asked about how I approached different things, so I told to come by my place for a little workshop. I didn't charge him, but now he's a student who I see on a weekly basis (I charge him now).
Also, I have 34 students now and they are getting fabulous instruction as witnessed by how well they are doing. 6-12 students wouldn't put enough bread on my table that's for sure.
I have been teaching in Japan for now over 5 and a half years. But I still only have 5 students. Can you believe that? I don't know what I'm dong wrong. I Japanese have improved very much and I don't have much of a language barrier. I have put ads out before but no luck. I'm really bumbed out right now. And I even applied for jobs at music universities but they are firing teachers because of lack of students. I'm really in a bind. I'm beggining to think that I've made a mistake coming to this country. So instead of piano, my real occupation, I am teaching mostly English and Korean, which I hope I won't have to once my studio has grown. But the question is when.Anyway, I'm in a real slump in my life. Compared to me you are still fine. I'm still looking at the bright side. After all, I've only been here five and a half years with only 5 students.......yeah, right.
