Probably no other musical instrument（乐器）is as popular around the world as the guitar. Almost every kind of music needs a guitar. Country and western music would not be the same without a guitar. The Spanish music called flamenco could not exist without, a guitar. The sound of American blues music would not be the same without the sad cry of the guitar. And rock and roll music would almost be impossible without this instrument.

　　People do not agree about where the guitar was first played, but most agree it is very old. Some say an instrument very much like a guitar was played in Egypt more than one thousand years ago. Some others say that an old form of the modem guitar was brought to Spain from Persia sometime in the 12 century. The guitar continued to develop in Spain. In the 1700s it became similar to the instrument we know today.

　　Many famous musicians played the instrument. The famous musician Niccolo Paganinni played and wrote music for the guitar in the early 1800s. Franz Schubert used the guitar to write some of his famous works. In modem times Andres Segovia helped make the instrument extremely popular.

　　One kind of music for the guitar developed in the southern area of Spain called Adalusia. It will always be strongly connected with the Spanish guitar.
