About guitars

A guitar is a music instrument that is found in variety of types. A guitar usually has six strings, although there are guitars with seven, eight and twelve strings. The string set will define the range of tunes that one can play on the quitar, or play comfortably. A discant guitar has usually 6 strings and is suited for playing middle to high tunes. A bass guitar has usually 4 strings and can play from middle to low tunes.

The classical accoustic guitar with six strings as we know it today is of Spanish origin. A guitar player is commonly called a guitarist. Guitars are most often used to accompany song or dance, but guitars with six or more strings are also used as solo instruments. The guitar is one of the most important instruments in blues, country, flamenco, rock and many forms of pop music.

The tones of an accoustic guitar are produced by vibration of the strings and amplified by a resonance box. In an electric guitar the vibrations of the strings will cause magnetic vibrations that are then converted to electric vibrations in a pickup-unit and then the electric vibrations are amplified by using an electrical amplifier, which can also alter the volume and quality. The electric guitar was invented in the first half of the 20 century, and had and still has great significance in popular culture. There are also hybrid guitars that both use accoustic amplification by a hollow box and electromagnetic amplification.

History of the guitar
Instruments similar to the guitar, has been in use for at least 5000 years. Presumably, it has evolved from the ancient Indian instrument sitar. The oldest depiction of an instrument that can be said to be a guitar, is a 3300 year old carving in stone of a hettite musician. The word guitar is from the Spanish guitarra, which has roots in the Latin word cithara, which in turn derives from the old Greek word kithara, which possibly came from the Persian word sith, which in turn is related to the Indian instrument.

The modern guitar is developed from the instrument cithara, which the Romanis brought to Spain around the year 40, with influence from the Persian oud from the 8th century. Elsewhere in Europe was the six string Scandinavian lute common in areas that had contact with the Vikings. At the beginning of the 13th century had two guitar types had evolved: guitarra in quiet, which had a rounded back, wide neck and several sound holes in the body, and the guitarra latina, which is like the modern guitar, with its narrow neck and one sound hole.

Acoustic guitars
An acoustic guitar, or "acoustic guitar" is a box or body of tree, where the lid is usually of conifers such as spruce or cedar, while the neck, Sarge and bottom are made of different types hardwood such as maple, rosewood (palisander), mahogany and so on. The guitar consists of the wooden resonance box with holes, a chair where the strings are attached, and a neck with ribbons marking the notes and serving as fixing points for the strings when the guitarist pushes down a string. A guitar of this type is called a classical guitar or an coustic guitar. But one can put a microfone into it to catch the sound.

Classical guitars have nylon strings, but it is now also common with steel guitars needed.

Electric guitars
An electric guitar or "plank guitar" has most often body in solid wood, although it also can be equipped with a cavity (semi-hollow or hollow body). Electromagnetic microphones are converting vibrations of metal strings into electrical signals which are entered into an amplifier through a cable or a wireless radio system. The electric guitar had their commercial breakthrough with such Gibson ES 175, L5, and other hollow body guitars in which there were mounted microphones in the 1930 40th century, within the jazz genre. Guitars with solid wood came later with Leo Fender Telecaster, and Gibson's collaboration with Les Paul.

Musical construction
Common to the above-mentioned types of guitar is that they all usually have six strings. On the guitar "head" is the voice screws to keep the instrument tuned, and the normal tuning is in quarters from E to A, A to D, etc., while the interval from G-string is only one third up to H, which in turn is followed of an E. Standard tuning for the six strings are therefore tones (from lowest to highest) E-A-D-G-H-E. As an aid to remember the tones one uses often the phrase "The other day he went Lonely", ev. "Eddy Ate Dynamite, Good Bye Eddy".


Guitar also comes with twelve strings (twelve needed guitar), arranged in six string pairs where the deepest strings are tuned in octaves.

Voting
Many also use the voice of the guitar to open tuning, where the strings voted in a chord, usually a major-chord (eg. Open G: D-G-D-G-B-D). This is widely used in blues with the use of slide or bottleneck, a metal or glass tube that rests on the strings and make the print without touching the neck.

The guitar is an ideal compromise instrument for use by the accompaniment of the song or a melody instrument, but is also a well-known solo instrument. It was particularly classical composers such as Fernando Sor and Maurio Guliani who was able to contribute guitar compositions of higher quality. Their sonatas and etudes played today.

Learning Process and uses
You can play a guitar in several ways, as a complete instrument or a solo instrument. The first thing one learns is usually to play chords. Just like regular notes, so there are C, D, E, F, G, A-and H-chords, with semitones: C ♯, D ♯, F ♯, G ♯, A ♯ and A ♯ . Chords are divided into Dürer, a major for each chord. C major: C, F and G. D major: D, G and A. E major: E, A and H. F major: F, B ♭ (B lowered half tone), and C. G : G, C and D. A major: A, E and D. B major: H, F ♯, and E.

All the chords have their own minor.
