Why do strings have a hollow body?

Answer 1

Same reason why acoustic Guitars are hollow... the "acoustics" the sound it makes... its what makes the violin sound as it does.

Example: blow air across the opening of a small empty soda bottle you get one sound, blow air across the opening of a large empty "whisky" bottle, and you get a deeper sound.

the size of the cavity changes how the instrument sounds, which is why the viola and chello sound deeper than a violin, but they are nearly identical in design, if just for larger proportions.

while you can have an "electric" violin, just like electric guitars, the original sound was created and made because of how the instrument was shaped, hollowed, and strung. Electric versions of these instruments sound similar but can take sound into a completely different direction than the original acoustic versions of the instrument.

Answer 2

Put simply, the body of an acoustic guitar is hollow because the sound waves produced when you strum or pick the strings resonate inside the guitar's body, which produces your guitar's volume and certain aspects of its tone.

Answer 3

the hollow body of an acoustic guitar is because of the fact that the sound has to have somewhere to bounce around and amplify itsself. its sort of like this. when you go to the mouth of a cave and scream it echos and bounces around and comes back to you. hope this helps - Kyse

Answer 4

in all hollow body guitars, the reason for being hollow is sound amplification. if you haven't noticed, on fender stratocasters, a non-hollowbody Electric Guitar, you cannot hear the guitar without an amp. if it was hollow, like most gretsch guitars, then you would not need an amp to hear it well.

Answer 5

So any vibrations/sounds you make with the strings are focused and echo/resonate through the body to make the sound louder
