Steel bar

A steel bar, also called slide, play bar and bottleneck, is a musical apparatus which is used to play on steel guitars. The steel bar can be wound around the fingers or just held in the hand. Instead of pressuring the strings on the neck of the guitar, the steel bar slides over the strings, which produces a glissando effect.
