KeyBored is a program that turns every letter or number you type into a musical note. Each row on a QWERTY keyboard is an octave, with Z being lowest and the number row highest. Holding shift makes the note sharp.

This pretty pimp. Gives everything you type this melodic sound. Kinda annoying sometimes though. Depends on what you write.
