Musical Arrays

What does a rectangle with an area of 15 centimeters squared, and a perimeter of 16 centimeters sound like? 

How would the sound change if the area stayed the same, but the perimeter changed?

Music Board begins with a black grid. When users click squares, they light up and play musical notes.

According to the game's creator, Music Board is a "free, open source game." Computers and software cost money, but there are lots of creative souls out there who believe it all should be free. For everyone.
