The f-holes of a violin: quick facts
The f-holes are the two sound holes carved into the top of a violin, named for their resemblance to the letter 'f'. They allow air to move in the body and play an important role in how the instrument radiates sound; research has shown their elongated shape helps project power efficiently. For experts, the exact cut, length, and placement of the f-holes are among the surest signs of who made an instrument, since each maker shaped them in a personal way. Stradivari's f-holes are admired for their elegance and precision. Studying them is central both to authentication and to understanding why the great Cremonese violins sound and look as they do.
