We are going to pay for lessons. I learned at age 4 and took lessons and played until I was 16. We recently got a piano and my son (3.5) is eager to learn. I sat with him and realized I have no CLUE how to teach him. Moreso, he probably won't sit and learn from me. There are apps now and iPad programs, but I sort of want him to learn the old fashioned way.
I think we will pay for lessons now, and once he can read music and play then I will take over.

But getting started, I have no idea.
