How much does it cost for a guitar lesson for a beginner?

Depends on where you live and how long the lesson is — half hour or hour? It also depends on who the teacher is — an established, in-demand guitar teacher can charge a bit more, an impoverished college music major looking to pick up some extra money will most likely charge less.

I would say that for a half hour lesson, you should expect to pay between $15 – $20. For an hour, $35 – $40. That's assuming YOU travel to where the lessons are being given, at the teacher's home or studio or music store. If you want the teacher to come to you, he or she might charge a bit more to cover their travel time and gas, say $20 – $25 for a half hour, or $45 – $50 for an hour.
