An instrumental is, in contrast to a
song, a
musical composition or piece without
lyrics or any other sort of
vocal music; all of the
music is produced by
musical instruments. These instruments include anything
in the range of
strings,
woodwinds,
brass, and
percussion. Specifically, this term is used when
referring to
popular music; some
musical genres make little use of the
human voice, such as
jazz,
electronic music,
classical, and large amounts of
Western classical music (although in electronic music,
the voice can be sampled just like anything else). In
commercial music, some tracks or songs on a
compact disc include instrumental tracks. These tracks
are exact copies of the corresponding song, but do not have
vocals.
