LOL, why not show a picture of how the piano works?

@Blurred_Lines Thank you for pointing that out. I didn't know that either. Tried it, but not a good feature. Still not convenient. lol

JY is such a troll for not showing the full question first. And for what?? Wasting time??

Why not have all the answer options visible first? A,B,C,D,E... That way I try it myself first. Then compare with the video tutorial or the written explanation. Now the order is all jumbled

Uhhh, are JY and Kevin the same person? They sound the same. LOL
