The top, back and ribs of an acoustic guitar body are very thin (1–2 mm), so a flexible piece of wood called lining is glued into the corners where the rib meets the top and back. This interior reinforcement provides 5 to 20 mm of solid gluing area for these corner joints. Solid linings are often used in classical guitars, while kerfed lining is most often found in steel string acoustics. Kerfed lining is also called kerfing because it is scored, or "kerfed"(incompletely sawn through), to allow it to bend with the shape of the rib). During final construction, a small section of the outside corners is carved or routed out and filled with binding material on the outside corners and decorative strips of material next to the binding, which are called purfling. This binding serves to seal off the end grain of the top and back. Purfling can also appear on the back of an acoustic guitar, marking the edge joints of the two or three sections of the back. Binding and purfling materials are generally made of either wood or plastic.
Our intermediate and advanced guitar lessons are tailored to build on the skills that students have developed through their previous beginner lessons and programs. These programs pair private guitar lessons with full-band group rehearsals and live performances, allowing student guitarists to showcase their skills by playing advanced songs from famous musicians. Our world-class guitar instructors and teaching system are proven to help students play and perform at a higher level.
As a beginner guitar player, one of the most difficult hurdles to overcome is that of transition between chords. We learn the chords to our favourite songs or a new complex chord shape, but when it comes to making music with them, our lack of muscle memory and dexterity inhibits us from stringing these chords together in a meaningful and comprehensive manner.

Adjusting the truss rod affects the intonation of a guitar as well as the height of the strings from the fingerboard, called the action. Some truss rod systems, called double action truss systems, tighten both ways, pushing the neck both forward and backward (standard truss rods can only release to a point beyond which the neck is no longer compressed and pulled backward). The artist and luthier Irving Sloane pointed out, in his book Steel-String Guitar Construction, that truss rods are intended primarily to remedy concave bowing of the neck, but cannot correct a neck with "back bow" or one that has become twisted.[page needed] Classical guitars do not require truss rods, as their nylon strings exert a lower tensile force with lesser potential to cause structural problems. However, their necks are often reinforced with a strip of harder wood, such as an ebony strip that runs down the back of a cedar neck. There is no tension adjustment on this form of reinforcement.


The electric guitar initially met with skepticism from traditionalists, but country and blues players and jazz instrumentalists soon took to the variety of new tones and sounds that the electric guitar could produce, exploring innovative ways to alter, bend and sustain notes. The instrument's volume and tones proved particularly appealing to the enthusiasts of rock and roll in the 1950s.
