GUTAR.....
The guitar strings are plucked with the fingers and fingernails of the right hand (or left hand, for left handed players), or a small pick made of thin plastic. This type of pick is called a "plectrum" or guitar pick. The left hand holds the neck of the guitar while the fingers pluck the strings. Different finger positions on the fretboard make different notes.
Guitar-like plucked string instruments have been used for many years. In many countries and at many different time periods, guitars and other plucked string instruments have been very popular, because they are light to carry from place to place, they are easier to learn to play than many other instruments. Guitars are used for many types of music, from Classical to Rock. Most pieces of popular music that have been written since the 1950s are written with guitars.
There are many different types of guitars, classified on how they are made and the type of music they are used for. All traditional types of guitar have a body which is hollow. This makes the sound of the strings louder, and gives the guitar its quality. This type of guitar is called "acoustic". (An acoustic instrument is one that makes its own dynamics.)
From the 1930s, people started making and playing guitars that used electricity and amplifiers to control the loudness. These guitars, which are often used in popular music, are called electric guitars. They do not need to have a hollow body. This is because they do not use acoustics to amplify the sound.
Most guitars have six strings, but there are also guitars with four, seven, eight, ten, or twelve strings. More strings make the instrument sound fuller. The neck of a guitar has bars or marks called frets. Frets help a guitarist know where to put his or her fingers to get the right pitch when playing.
