In music theory, the word inversion has several meanings. There are inverted chords, inverted melodies, inverted intervals, and (in counterpoint) inverted voices. The concept of inversion also plays a role in musical set theory.
An interval is inverted by raising or lowering either of the notes using displacement of the octave (or octaves) so that both retain their names (pitch class). For example, the inversion of an interval consisting of a C with an E above it is an E with a C above it - to work this out, the C may be moved up, the E may be lowered, or both may be moved.
Under inversion, perfect intervals remain perfect, major intervals become minor and vice versa, augmented intervals become diminished and vice versa. (Double diminished intervals become double augmented intervals, and vice versa.) Traditional interval names add together to make nine: seconds become sevenths and vice versa, thirds become sixes and vice versa, and fourths become fifths and vice versa. Thus a perfect fourth becomes a perfect fifth, an augmented fourth becomes a diminished fifth, and a simple interval (that is, one that is narrower than an octave) and its inversion, when added together, equal an octave. See also complement (music).
Inversion was a 2005 artwork by sculptors Dan Havel and Dean Ruck of Houston Alternative Art.
Havel and Ruck altered two buildings owned by the Art League of Houston on the corner of Montrose Boulevard and Willard Street. The exterior skins of the houses were peeled off and used to create a large vortex that funneled into the small central hallway connecting the two buildings and eventually exited through a small hole into an adjacent courtyard.Inversion has become one of Houston’s most well-known, albeit vanished, sculptures. The structure was later demolished to make way for a new Art League building.
Art League Houston owned the two houses and had used them for art classes and exhibitions for over 30 years. The organisation commissioned Havel and Ruck to transform them into an artwork in demolition. The sculpture was opened on May 21, 2005, and was visible from Montrose Boulevard until its demolition the next month.
Years later, the artwork continues to be cited on design blogs.
In evolutionary developmental biology, inversion refers to the hypothesis that during the course of animal evolution, the structures along the dorsoventral (DV) axis have taken on an orientation opposite that of the ancestral form. As early as 1822, the French naturalist Étienne Geoffroy Saint-Hilaire noted that the organization of dorsal and ventral structures in arthropods is opposite that of mammals. Five decades later, in light of Darwin's theory of "descent with modification", German zoologist Anton Dohrn proposed that these groups arose from a common ancestor which possessed a body plan similar to that of modern annelids with a ventral nerve cord and dorsal heart. Whereas this arrangement is retained in arthropods and other protostomes, in chordate deuterostomes, the nerve cord is located dorsally and the heart ventrally. The inversion hypothesis was met with criticism each time it was proposed, and has periodically resurfaced and been rejected. However, some modern molecular embryologists suggest that recent findings support the idea of inversion.

"Music" is a short story by Russian American author Vladimir Nabokov originally published in Russian in 1932.
The story uses third-person narration and tells the story of Victor, a self-conscious man for whom "music he did not know... could be likened to the patter of a conversation in a strange tongue." When Victor arrives at a party, he finds the other guests listening with varying degrees of engagement to a man named Wolfe play the piano. As Victor does not know the song being played, he loses interest. He catches a glimpse of his ex-wife at the party, but cannot look at her. He laments the fact that now he must "start all over" the long task of forgetting her (in a flashback, it's revealed that she left him for another, who may or may not be at the party). Throughout the entire story, Victor views the music as a structure that has him encaged in an awkward situation with his ex-wife; it had seemed to him "a narrow dungeon" until it ends, thus giving his ex-wife the opportunity to leave, which she does. Victor then realizes that the music was not a dungeon, but actually "incredible bliss, a magic glass dome that had embraced and imprisoned him and her," and which allowed him to "breathe the same air as she." After she leaves, another party-goer comments to Victor that he looked immune to the music and that he didn't think such a thing possible. His own inanity is revealed when Victor asks him what was played and he cannot tell whether it was Beethoven's Kreutzer Sonata or Tekla Bądarzewska-Baranowska's rather easy piece, Maiden's Prayer.
"Music" is a 2001 hit single by Erick Sermon featuring archived vocals from Marvin Gaye.
The song was thought of by Sermon after buying a copy of Gaye's Midnight Love and the Sexual Healing Sessions album, which overlook some of the original album's earlier mixes. After listening to an outtake of Gaye's 1982 album track, "Turn On Some Music" (titled "I've Got My Music" in its initial version), Sermon decided to mix the vocals (done in a cappella) and add it into his own song. The result was similar to Natalie Cole's interpolation of her father, jazz great Nat "King" Cole's hit, "Unforgettable" revisioned as a duet. The hip hop and soul duet featuring the two veteran performers was released as the leading song of the soundtrack to the Martin Lawrence & Danny DeVito comedy, "What's the Worst That Could Happen?" The song became a runaway success rising to #2 on Billboard's R&B chart and was #1 on the rap charts. It also registered at #21 pop giving Sermon his highest-charted single on the pop charts as a solo artist and giving Gaye his first posthumous hit in 10 years following 1991's R&B-charted single, "My Last Chance" also bringing Gaye his 41st top 40 pop hit. There is also a version that's played on Adult R&B stations that removes Erick Sermon's rap verses. The song was featured in the 2011 Matthew McConaughey film The Lincoln Lawyer.
