Learn piano online - child

Ddigger

I bought an old Roland HP 88 key piano off Gumtree a couple of years ago at a great price.  The boy (6 in April) can follow along a child's music book as long as he knows the tune.

As schools are now shut, can anyone recommend an age appropriate you tube channel or dedicated piano learning app?

Although the missus might disagree, I do play guitar and know some music theory, but can't read music. We were thinking of trying out real piano lessons after the summer anyway.

Thanks, Ddig
