A guitar is a plucked string instrument, typically with six strings, similar in shape to a violin.

The guitar is often regarded as the main instrument in pop music, rock music, blues, folk songs, and flamenco. In classical music, guitars are often performed as solos or duets. Of course, in chamber music and orchestral music, the guitar also plays a considerable degree of foil role.

The ancestors of the guitar can be traced back to two or three thousand years ago in ancient Egypt, Nepal, Babylon, and Persia, with all kinds of ancient plucked instruments.

The guitar and Bivera masters at that time included Milan, Nalevais, and Mandala, as well as the five groups of complex string Baroque guitar masters in the 17th century, such as Sanse, Corbetta, and Vishay.

Many of their works remain immortal treasures in the modern classical guitar repertoire. At that time, the musical notation used by guitars, Biviras, and other instruments was not the current staff notation.

Instead, horizontal lines were used to represent each string, and numbers or letters were used to represent phonological positions and fingering, which was similar to the hexagon notation used in folk guitars today.
