What are Guitar Strings?.. A guitar string is a string made of a particular material, typically, gut, nylon or steel, which is spanned over a wooden instrument or an instrument which has magnetic or piezoelectric pickups. The purpose of the string is to vibrate and produce a particular musical note. A standard guitar has 6 strings and is tuned in the following configuration, E-A-D-G-B-E. For the wooden or acoustic guitars, the sound is produced by the vibration of the strings which is amplified by the wooden body of the guitar.
