How can I learn piano chords and scales quickly and easily?
On the piano, you don’t really need a “CAGED” method because the octaves are much easier to visualize. You just have to be able to see the group of two black keys versus the group of three black keys as you move up and down the keyboard. For example, the note between the two black keys, anywhere on the keyboard, is D. This is one reason I moved from guitar to piano some years back and stayed with the piano. It was so much easier to visualize every note on the piano, and I’m a visual person.
