Let's hear those scales
I have to say, this is an interesting take on the floor piano idea.
I only wish it was capable of something more than the F-sharp major scale. (Actually, those of you with perfect pitch will notice that the fellow who starts walking up the stairs at 0:41 is accompanied by the right notes. I wonder why everybody else gets F-sharp major?)
The other thing the staircase needs, of course, is a bit of order to prevent it from descending (ha ha, get it?) into a giant cacophony. To that end, I’d like to propose the following rule: “You must maintain a distance of exactly two, five, or seven steps behind the person in front of you. If you follow exactly four steps behind, you will be asked to navigate the Prok 2 finale.”
