So his teacher tells him to memorize the pieces. Good I think, so I have him go memorize each piece and give me a concert once a day. He's like 40% of the way there now, better but no where near close.
So his teacher now says go learn with your eyes closed. _This_ made the difference. He plays with the correct rhythm, corrects any mistaken notes because well mistakes compound, even his dynamics sound right now. It's actually beginning to sound like actual music!
For him I think closing the eyes got him out of his mentality of just rushing the pieces, it put him out of his comfort zone and that has made all the difference.
