in california here they can charge around $100 a month for a half hour lesson per week... that's $50 an hour! of course, the cost of living in california is alot higher then in most other states, so it evens that out I guess. so you would probably need 40+ students just to get by comfortably

but yeah, if you have a bachelors in music, it would be alot easier to get a higher clientele. think about it, would you rather take lessons from someone who has taken college level music courses and has his bachelors, or someone that claims to have figured it all out on their own?
