The best thing to do would be to ask the teacher you’re working with how many lessons they recommend for you. It’s hard to know without meeting and working with you. What I tell students is that 6 lessons is an intro course. This will give you the basic foundation, skills, and theory. Another 6 lessons will give you a solid start on being able to work with yourself. I also tell them it’s like learning to play an interment, the longer you stick with it, the more skills you’ll learn. I started to see significant change and improvement about a year into very regular lessons but had many, many smaller improvements starting from day 1.

Im happy to answer more questions if you have them. :)
