The key of F is the key of such glorious instruments as the cello, the trombone, the bassoon, the bass, and most male voices and choirs. It also happens to be the key in which is written the lef hand of the harp and every keyboard instrument. It is the hand that you don't notice much, although it carries the whole music on its shoulders, if I may say. Both harmony and rythm rely on the left hand. The man who invented rock'n'roll piano, Jerry Lee Lewis - also known as The Killer - portrays himself as having "music in his soul, rythm in his blood and a lotta thunder in his left hand".
Changing a lotta furry into a lot of fur, in 1999, I designed this key of F (below) as part of an eery and hairy typeface called "fur".

The
furry effect was achieved with the help af a professional art software called Painter 6 (
MetaCreations corp), which I also helped develop. One of its functions imitates grass. Or fur, if you choose a brownish tone.
Another function has the funniest name : "automatic Van Gogh" ! And it works ! When you apply this digital filter, the picture instantly gets covered in small, thick, color saturated strokes that makes it strikingly resemble a Van Gogh painting. And you don't even have to cut off your ear.
