Tuning: A variety of different tunings are used. The most common by far, known as "standard tuning" (EADGBE), is as follows: sixth (lowest tone) string: E (a minor thirteenth below middle C—82.4 Hz) fifth string: A (a minor tenth below middle C—110 Hz),fourth string: D (a minor seventh below middle C—146.8 Hz), third string: G (a perfect fourth below middle C—196.0 Hz),second string: B (a minor second below middle C—246.92 Hz),first (highest tone) string: E (a major third above middle C—329.6 Hz)

The classical guitar is distinguished by a number of characteristics: It is an acoustic instrument. The sound of the plucked string is amplified by the soundboard of the guitar which acts as a resonator. It has six strings. A few classical guitars have eight or more strings to expand the bass range, and to expand the repertoire of the guitar. The three treble strings are made from nylon, as opposed to the metal strings found on other acoustic guitars. Nylon strings also have a much lower tension than steel strings, as do the predecessors to nylon strings, gut strings (made from ox gut). The lower three strings (bass strings) are wound with metal, commonly silver plated copper. Because of the low tension of the strings the neck can be made entirely of wood, not requiring a steel truss rod. The interior bracing of the sound board can be lighter, due to the low tension of the strings. This can allow for more complex tonal qualities. A common classical guitar bracing pattern is the fan bracing. A centre spruce brace is glued on the inside of the soundboard along the centre line of the guitar to just before the bridge. Additional braces fan out on ether side of the first brace. A typical modern six-string classical guitar has a width of 48-54 mm at the nut, compared to around 42 mm for a modern electric guitar design. The classical fingerboard is normally flat and without inlays, whereas the steel string fingerboard has a slight radius and inlays. It’s bigger than the common classical guitar.
