12-string guitar

The twelve string guitar is an acoustic or electric guitar with twelve strings, which produces a richer, more ringing tone than a standard six string guitar. Essentially, it is a type of guitar with a natural chorus effect due to the subtle differences in string timbre.The strings are placed in courses of two strings each that are usually played together. The two strings in each bass course are normally tuned an octave apart, while each pair of strings in the treble courses is tuned in unison. The tuning of the second string in the third course (G) varies: some players use a unison string which is less prone to breakage, others prefer the distinctive high-pitched, bell-like quality an octave string makes in this position.
