Stay away from big box lessons (guitar center, etc.) The quality of instruction is typically poor and the fees structure of what they charge teachers is predatory and almost exploitation and it definitely degrades the experience.

Go private. It's built for long term relationships and learning.

There's a co-op studio in Cockeysville of private teachers that don't compete with one another for students but also doesn't have that fee structure, so you're getting your money's worth and so is that teacher. Find something like that.
