Slide guitar or bottleneck guitar is a particular method or technique for playing the guitar. The term slide refers to the motion of the slide against the strings, while bottleneck refers to the original material of choice for such slides: the necks of glass bottles. Instead of altering the pitch of the strings in the normal manner (by pressing the string against frets), a slide is placed upon the string to vary its vibrating length, and pitch.
