I hope you enjoy becoming reacquainted with the piano. I must say that 5 seems awfully young to start -- assuming you are not planning on being a concert pianist. I started at 7 and stopped at 11 because once I transferred to grammar school, it was difficult to fit in the practice. But really, I wasn't that motivated and preferred the recorder (graduating to treble) and the guitar.

Now I just make do with guitar and ukelele, though I do have an electronic keyboard at the back of the cupboard which I haven't played for many years.
