When you're a certain grade, you can start playing harder songs and please tell your teacher if you can play this song because usually in piano you play jazz and mozart songs. ps. Jazz songs are extremely fun but I recommend them for Grade 3.
If you work hard, you will be able to play these songs. There are thousands of other songs you can play too!
By the way I play piano and sometimes I feel like giving up but when I listen to these songs, i get over it. :) :)
Thank you for reading and listening. Bye :)
