Not quite. You're given a list of n options and you number them 1 to n. If your number 1 option is the lowest minority your vote then becomes what you selected as number 2, and it continues this way until a clear consensus with >~51% votes is found.
I'm not sure about how to go about creating a metronome, but you can also mix in a Green Greens music in the background of the metronome to make sure people stay on course and sing at the right speed and emphasis. With everyone singing to the same metronome syncing is dead easy.
A metronome is just a periodical beat, I guess anything could work, even if it means tapping two spoons together into your mic.
Yep, i was thinking it would be more fair since it would mean everyone's choices are taken in consideration.
I was thinking more like how to have a metronome in time for everyone to sing to online? Is there a site that syncs the video to a video or something? If not. I'll figure it out.
