DD4 started piano lessons when she just turned 4 and key span was a bit of a problem. It has been 3 months and she now has a 5 key span.

Russian method. Learn to read notes, play music pretty much off the bat. She memorizes, corrects by ear, but tends to memorize rather than read the notes. She learns a piece a week, according to this teacher. And he wants her to do a recital after a couple of months. DD was resistant but she is going to do one in another couple of months.

It is really great for the fine motor skills, learning to do the scales with both hands, getting the middle finger over the thumb, to play the scales. It is amazing how rapidly she progresses with her abilities with her hands, though she does love to play her pieces.
