The Encyclopedia of Science Fiction notes that future fictional instruments are generally either "variants on traditional instruments and those that exploit future technology". • In the
Futurama television series, a fictional musical instrument called "the
Holophonor" was introduced. It resembles an oboe and produces holographic images that respond to the mood of the performer. It has been suggested that this instrument, while currently fictional, might be constructed in the near future given the current trends in technology. • The aforementioned
Hydrogen Sonata of Iain M. Banks can be performed only on a complex instrument called the Antagonistic Undecagonstring, which requires not only two feet for its pedals but also four arms. • The rock band
Disaster Area, featured in
The Hitchhiker's Guide to the Galaxy, play the "massive" photon-ajuitar (its name suggesting a
guitar-like instrument, but also described as having a keyboard), the bass detonator, and the Megabang drum complex (often needing to be played by a robot due to the absence of the band's drummer). Hypothetical musical instruments using live animals, intended as
thought experiments or as bizarre humour, include the
cat organ and the
piganino. == See also ==
