Have you tried the Skip Song (Duet #1) from Primary Prodigies yet? We did, and it was so much fun! Boo played his part (Re, Fa, La, Do). I played mine (Do, Mi, Sol, Ti), and then we came together on the chords.
Playing Duets like this is a great way to get involved in your child's musical journey! Splitting up the bells is also a really easy way to make 5-8 note songs a lot easier!
Check out Boo and I playing Primary Prodigies Duet #1 for a great look at how you and your kids can enjoy Prodigies together!
