Just as there are different types of guitars, there are different types of strings. Here are the principal types:

• Nylon strings are used on classical guitars. In fact, it is dangerous to use heavier strings on a classical guitar, because the instrument is not designed to withstand the high tension they produce. The three lowest strings are made of silver-plated copper wire wound on a core of nylon strands. The upper three are pure nylon filaments.
• Steel strings are designed for acoustic folk guitars. The bass strings are wound on a core of silk or nylon.
• Heavier wound metal strings are designed for electric guitars.

Core and winding materials vary among string makers, and you may wish to experiment with different types to see which produces the sound you like best.Strings are also available with different shapes or contours, from flat to fully rounded. Strings are also sold in light, medium, or heavy gauges. This has to do with the amount of elasticity in the string: light-gauge strings are more elastic and therefore easier to play than heavy ones. Again, depending on the kind of music you play and your own personal taste, you’ll be able to choose the proper string for you. It’s always worthwhile to try different types of strings on your instrument to see if a simple change of strings can lead to improved sound and playability.

This is the type of guitar that developed from the earliest forms of fourand five-stringed instruments, reaching its final form in the early nineteenth century. In addition to being the type of guitar used for the solo “classical” repertoire, the Spanish or classical guitar is used for the accompaniment of folk songs, for the songs and dances of Latin America, and for the flamenco music of Spain. Throughout Europe it has long been the favorite accompaniment instrument for love songs and serenades.

Traditionally the sides and back of a flamenco guitar differ in that they’re made of cypress wood, which is distinguishable by its yellow color and lighter weight, but this is not always the case today because some of the great flamenco players prefer hardwood.

Classical guitars usually have a slotted peg head and are strung with nylon strings. Generally they are smaller than acoustic or electric instruments. The neck width is greater than on acoustic or electric guitars to facilitate the intricate left-hand work demanded in classical compositions.

Although the term “acoustic” really applies to any non-amplified guitar, it is commonly used to describe the steel-strung guitar used in country, folk, and blues styles. The steel strings give more volume than nylon, and also have a “brassier” sound.
