wow!! this is really cool!  i found and counted the Cs, there's 8 Cs on my whole piano! i pressed a lot of the Cs and i noticed they all sound kind of the same, like, i don't know what its called but all of them have similar tone feel to it  i think. but, when i pressed them in order from left to right, each C went some pitch higher than the last C. thats amazing!! i think im ready for the next step, what should i do now?
go to the middle of the keyboard. take every white note from C to the next C. so that should be 8 notes (c, d, e, f, g, a, b, c). Now, see what songs you can play! just using those notes. hint: start with like popular kids songs
