My DS aged 9 has recently done his Grade 4 exam. He's a bit bored with it all so I'd like him to spend some time playing music he actually enjoys and forget about grades for a while. My problem is that I don't know anything about music and DS won't have a piano teacher now until September. I definitely want to keep him going with some fun pieces. He enjoys blues in general although it can get a little repetitive, upbeat songs and also likes Apologize and Counting Stars by OneRepublic. I was wondering if anybody could recommend some grade appropriate tunes for my DS to work these next few months. Please be as specific as you can and send links if possible as I am not able, from looking at the music sheet, to gauge the grade. Thanks so much.
