Sight read often
Believe it or not, sight reading can be fun. Not convinced? Dig out your old music books from a year or two ago and try playing through a few of the pieces you didn’t learn at the time. Not only is this good sight reading practice, it’s a good way to keep playing during the holidays. PLUS you’ll learn new repertoire that you might enjoy AND you’ll give yourself a confidence boost by sight reading music you once thought was impossible.
