Experimental rock, also known as
avant-garde rock or
avant-rock, is a type of music based on
rock music which experiments with the basic elements of the genre, or which pushes the boundaries of common composition and performance technique. Performers of experimental rock may also attempt to individualize their music with unconventional
time signatures,
instrumental tunings, unusual harmony and key signatures, compositional styles, lyrical techniques, elements of other
musical genres, singing styles, instrumental effects,
found objects, or custom-made
experimental musical instruments. Experimental rock may involve
extended techniques,
prepared instruments,
unconventional playing techniques, extended vocal techniques, and the use of
instruments,
tunings,
rhythms or
scales from non-Western musical traditions.
