All the sound of an acoustic guitar originates with the plucked strings. The rest of the guitar modifies that sound and makes it louder, but it cannot add anything to it. Strings, and the pick, picks, or the fingers/nails they are plucked with, are fundamental to the sound of a guitar. Since sound travels through the air and the small surface of the strings moves very little air, something is needed to move more air and make the sound from the strings louder. This is the main function of the guitar body. It acts as a mechanical amplifier, coupling the energy of the vibrating strings to the air around the guitar.
