This is a good piece for early beginning pianists and will most likely be featured in my upcoming Volume 3 of Play Piano For Kids.
The sheet music uses my color system which is basically a rainbow starting from C. You should download Play Piano For Kids, Volume 1 as a PDF to see the color scheme and how it works.
Most kids have heard of Beethoven and may have even been introduced to some of his music in their music class at school. Ode To Joy is the famous melody that was part of his 9th Symphony and there have been many versions of English lyrics put to this music over the last two hundred years.
And when you start teaching it to your child, you can have them listen to this version by a Philharmonic Chorus.
