Problem is for the first month of lessons it is not joy, it is hard frustrating work where you sound bad and know it. Even when you are good lessons often are pushing you to do hard things and so they are not pure joy.

My son has been taking violin for years, is really good, and loves it - but most of his practice time is still really hard pieces that need a lot of practice of the hard parts (stitching between 5th and 2nd position...) and he would prefer to sit down at the piano (he stopped lessons years ago) and play an easy piece.
