Music Derby

Virtually Maker Faire 2020

May 22nd-23rd

Music Derby is a game where you run 7 robots depending on the music and predict which robot will go the farthest when the song ends.
The sound of CDEFGAB (Do,Re,Mi,Fa,Sol,La,Si) is assigned to each of the four-legged robots that imitate animals such as deer, rabbits and mice.
For example, the note C is assigned to deer, the note D is to rabbits, and the note E is to mice.
When the note C is played, the deer will move forward. When the note D is played, the rabbit moves forward, and when the note E is played, the mouse moves forward.
When you play a Twinkle Twinkle Little Star in C major key, which animal will go the farthest when the song ends?
In C major, note C is the tonic, so you might expect the deer assigned to do to go the farthest.
However, in reality, the pig assigned to note G wins.
This is because the Twinkle Twinkle Little Star have the highest frequency of occurrence of the note G.
On the other hand, the cat does not move at all, because the note B never appears.
In this way, Music Derby can visualize the occurrence of notes on the scale in the song.
