Subgenre in the context of "Mythopoeia"

Speculative fiction is an umbrella genre of fiction that encompasses all the subgenres that depart from realism, or strictly imitating everyday reality, instead presenting fantastical, supernatural, futuristic, or other highly imaginative realms or beings.

This catch-all genre includes, but is not limited to: fantasy, science fiction, science fantasy, superhero, paranormal and supernatural horror, alternate history, magical realism, slipstream, weird fiction, utopia and dystopia, apocalyptic and post-apocalyptic fiction. In other words, the genre presents individuals, events, or places beyond the ordinary real world.

Noise music (or simply noise) is a subgenre of experimental music that is characterised by its use of unwanted noise as a primary musical element. The genre has roots in early 20th century avant-garde music, but later drew influence from industrial music. It is characterized by a rejection of conventional music theory and traditional song structures, often featuring little or no melody, rhythm, or harmony. This type of music tends to challenge the conventional distinction between musical and non-musical sound.

"Noise as music" originated as an avant-garde music style in the 1910s through the work of Luigi Russolo an Italian Futurist, who published the manifesto The Art of Noises in 1913. Elements of noise music were later explored by artists in the Dada and Fluxus movements, as well as through electroacoustic music, modern classical and musique concrète. Composers such as John Cage, Edgard Varèse and James Tenney would explicitly use the term "noise" to describe some of their experimental practices. During the 1960s and 1970s, compositions such as Robert Ashley's "The Wolfman" (1964) and Pauline Oliveros "A Little Noise In The System" (1967) were among the earliest examples of contemporary noise music. While works by non-academic artists such as Lou Reed's Metal Machine Music were influential for later noise artists.

Punk rock (or simply punk) is a subgenre of rock music that emerged in the mid-1970s. Rooted in 1950s rock and roll and 1960s garage rock, punk bands rejected the overproduction and corporate nature of mainstream rock music. Typically producing short, fast-paced songs with rough stripped-down vocals and instrumentation and an anti-establishment theme, artists embrace a DIY ethic with many bands self-producing and distributing recordings through independent labels.

During the early 1970s, the term "punk rock" was originally used by some American rock critics to describe mid-1960s garage bands. Subsequent developments such as glam and pub rock in the UK, alongside the Velvet Underground and the New York Dolls from New York have been cited as key influences. By the mid-1970s, the term "punk rock" had become associated with several regional underground music scenes, including the MC5 and the Stooges in Detroit; Television, Patti Smith, Suicide, the Dictators, Richard Hell and the Voidoids, and the Ramones in New York City; Rocket from the Tombs, Electric Eels and Dead Boys in Ohio; the Saints and Radio Birdman in Australia; and the Sex Pistols, the Clash, the Damned and the Buzzcocks in England. By late 1976, punk had become a major cultural phenomenon in the UK, giving rise to a punk subculture that expressed youthful rebellion through distinctive styles of clothing, such as T-shirts with deliberately offensive graphics, leather jackets, studded or spiked bands, jewelry, bondage clothing and safety pins.

Utopian and dystopian fiction are subgenres of speculative fiction that explore extreme forms of social and political structures. A utopia is a setting that agrees with the author's ethos, having various attributes of another reality intended to appeal to readers. A dystopia offers the opposite: the portrayal of a setting that completely disagrees with the author's ethos. Some novels depict both types of society to more directly contrast their properties. Both utopias and dystopias are commonly found in science fiction and other types of speculative fiction.

More than 400 utopian works in the English language were published prior to the year 1900, with more than a thousand others appearing during the 20th century. This increase is partially associated with the rise in popularity of science fiction and young adult fiction more generally, but also larger scale social change that brought awareness of larger societal or global issues, such as technology, climate change, and growing human population. Some of these trends have created distinct subgenres such as climate fiction, young adult dystopian novels, and feminist dystopian novels.

Freakbeat is a loosely defined subgenre of rock music developed mainly by harder-driving British mod groups during the British Invasion and Swinging London period of the mid-to late 1960s. The genre bridges R&B, beat and early psychedelia.

The lost world is a subgenre of the fantasy or science fiction genres that involves the discovery of an unknown Earth civilization. It began as a subgenre of the late-Victorian adventure romance and remains popular into the 21st century.

The genre arose during an era when Western archaeologists discovered and studied civilizations around the world previously unknown to them, through disciplines such as Egyptology, Assyriology, or Mesoamerican studies. Thus, real stories of archaeological finds inspired writings on the topic. Between 1871 and the First World War, the number of published lost world narratives, set in every continent, increased significantly.

High fantasy, or epic fantasy, is a subgenre of fantasy defined by the epic nature of its setting or by the epic stature of its characters, themes, or plot. High fantasy is usually set in an alternative, fictional ("secondary") world, rather than the "real" or "primary" world. This secondary world is usually internally consistent, but its rules differ from those of the primary world. By contrast, low fantasy is characterized by being set on Earth, the primary or real world, or a rational and familiar fictional world with the inclusion of magical elements.

Alternate history (also called alternative history, allohistory, althist, or simply A.H.) is a subgenre of speculative fiction in which one or more historical events have occurred but are resolved differently than in real history. As conjecture based upon historical fact, alternate history stories propose "what if?" scenarios about pivotal events in human history, and present outcomes very different from the historical record. Some alternate histories are considered a subgenre of science fiction, or historical fiction.

Since the 1950s, as a subgenre of science fiction, some alternative history stories have featured the tropes of time travel between histories, the psychic awareness of the existence of an alternative universe by the inhabitants of a given universe, and time travel that divides history into various timestreams.
