To understand the structure of the guitar, you need to understand the general types of the guitar. Many guitar fans interested in classical guitar, acoustic guitars, electric guitars, flamenco guitars, the appearance of the flamenco are similarity with classic guitars, but the acoustic structure was more suitable for flamenco style of music. Classical guitar and acoustic guitar the main part is consistent, but the appearance has a lot of difference. But the electric guitar compare with classical guitar and acoustic guitar, has a lot of difference.
The most prevalent differences are in the neck joints, the bridge designs, the bracing systems, and the nut widths.
Neck joint: The neck joins the classical/flamenco guitar at the 12th fret whereas it joins the steel-string guitars body at the 14th fret. The neck joint on classical/flamenco guitars are unified and built into the body. On a steel-string guitar, the neck is attached to the finished body with a dovetail joint, and usually has a truss-rod (running through the neck and into the body) for added reinforcement and intonation control.
Bridge design: On classical/flamenco guitars, the strings are strung through horizontal holes then tied. With steel-string guitars, the strings are usually secured by pegs wedged into vertical holes.
Bracing: The bracing on classical/flamenco guitars is usually of a radial fan system. Since the string tension of steel-strings is about three times greater than that of nylon strings, steel-string guitars usually employ a stronger, less efficient 'X' bracing system.
Nut Width: The nut width on classical/flamenco guitars is much wider than on steel-string guitars, usually by about 4 to 5 millimeters.
WHAT ARE THE DIFFERENCES BETWEEN CLASSICAL AND FLAMENCO GUITARS?
The differences between classical and flamenco guitars lie in their materials, construction and sound.
Materials: Classical guitars are generally made with spruce or cedar tops and rosewood or mahogany backs and sides to enhance sustain. Flamenco guitars are generally made with spruce tops and cypress or sycamore for the backs and sides to enhance volume and emphasize the attack of the note.
Construction: The body of a classical guitar is generally deeper and the woods are slightly thicker. Flamenco guitars have a flat or negative (before string tension) neck relief, making the action very fast at the cost of some buzzing. The strings are also closer to the body on flamenco guitars to facilitate tapping. Flamenco guitars often bear a "golpeador", which is a sheet of plastic mounted to the face of the guitar to protect its finish.
Sound: The classical guitar is designed to give the soloist the tools to perform poly-timbral music: "An orchestra in a box". The attack is soft with a longer and gradual decay. The flamenco guitar is designed to cut through the sound of dancers stomping their feet. The sound is a bit more percussive, a loud sonic burst followed by a swift decay.
