This is a second part of the duet. Primo part does not need to read. Just join with any rhythm and black key. ...
I composed this song for my 5 years old new student because I wanted her to play at my student recital within 2 weeks after she just started her piano lessons. She still could not read music yet, but she did performed with me ! The secret was..... the primo part can play any melody on the black keys. It's simple! You can try with my second part!!
