My son started cello at four, at a local music school for kids. Preucil School of Music He's still playing at 29. Still sounds good. Still enjoying it. He played simple songs at first, then more complicated ones. They were appropriate for where he was at, and he was happy to play them. They taught by ear, didn't read music for years. So he could work on sounding good from the start. Something he learned early was deliberate practice, where you go very slowly thru the song making sure each phrase sounds good. Then you speed it up and string the phrases together. In a few days you're playing full speed and sounding good. See, you never want to practice playing it badly. That trains you into playing bad music, and you have to undo the damage you just did to yourself.
