Lead guitar is a
guitar part which plays
melody lines,
instrumental fill passages,
guitar solos, and occasionally, some
riffs within a
song structure. The lead is the featured guitar, which usually plays single-note-based lines or
double-stops. In
rock,
heavy metal,
blues,
jazz,
punk,
fusion, some
pop, and other music styles, lead guitar lines are usually supported by a second guitarist who plays
rhythm guitar, which consists of accompaniment
chords and
riffs.
