The unison bend is a hugely expressive technique that usually features in blues, rock and metal styles. The sound is arguably unique to the electric guitar as the lighter string gauge allows each string to be independently manipulated without affecting the others. If your guitar has a vibrato system, any string bending will pull on the bridge and slightly flatten the other strings; this isn’t usually a problem, but is noticeable when performing unison bends. The technique starts as a double-stop played on adjacent strings; usually with first and third fingers playing the two notes a tone apart. Both strings are picked at once; the lower of the two is then bent up a tone, while the higher string stays where it is. This creates a pleasing microtonal dissonance between the notes, which sounds great with a distorted sound. Eventually the two strings will be playing the same pitch, hence the name ‘unison’.
