RicFreak...Good for you and your daughters. That's great to hear.
My 22year old son, got his first guitar 6 months ago, and asked if I could teach him to play a "song or two".
I told him I'd go one better and if he could devote the time to practicing, then I would teach him the basic understanding of his instrument...what the notes are, where to find them, how to find them and the mathematical relation to one another for chord building, and then it was up to him to do the intense work of repetition until it set in, but only if he wanted to.
I didn't know how he was progressing until 2 weeks ago. I was noodling on the keys when he dropped by, asked what I was playing, and if he could jam along. He picked up one of my acoustics and joined in on "Layla" in minutes.
Feels kinda Good.
