Classical Guitars: Building the Back (5 of 9)

The back has the traditional three cross structural braces found on most classical guitars. Added to this are the four parabolic braces in the two lower sections of the back. These additional braces add tremendous stiffness to the back with little weight gain. The purpose is to stiffen the back and use it for a reflecting plate and minimize the natural tendency of the back to absorb the sound energy. The sound energy is reflected back to the top where it belongs. The back plate material is thinned, as normal, so that it can still contribute to the tone quality of the guitar. The result is an increase in tone quality, overtone production, sustain and volume.
