What is "sequence"

Sequence \Se"quence\ (s[=e]"kwens), n. [F. s['e]quence, L. sequentia, fr. sequens. See Sequent.]

1. The state of being sequent; succession; order of following; arrangement.

   How art thou a king But by fair sequence and succession?
   --Shak.

   Sequence and series of the seasons of the year.
   --Bacon.

2. That which follows or succeeds as an effect; sequel; consequence; result.

   The inevitable sequences of sin and punishment.
   --Bp. Hall.

3. (Philos.) Simple succession, or the coming after in time, without asserting or implying causative energy; as, the reactions of chemical agents may be conceived as merely invariable sequences.

4. (Mus.)

   1. Any succession of chords (or harmonic phrase) rising or falling by the regular diatonic degrees in the same scale; a succession of similar harmonic steps.

   2. A melodic phrase or passage successively repeated one tone higher; a rosalia.

5. (R.C.Ch.) A hymn introduced in the Mass on certain festival days, and recited or sung immediately before the gospel, and after the gradual or introit, whence the name.
   --Bp. Fitzpatrick.

   Originally the sequence was called a Prose, because its early form was rhythmical prose.
   --Shipley.

6. (Card Playing)

   1. (Whist) Three or more cards of the same suit in immediately consecutive order of value; as, ace, king, and queen; or knave, ten, nine, and eight.

   2. (Poker) All five cards, of a hand, in consecutive order as to value, but not necessarily of the same suit; when of one suit, it is called a sequence flush.

7. the specific order of any linear arrangement of items; as, the sequence of amino acid residues in a protein; the sequence of instructions in a computer program; the sequence of acts in a variety show.

Sequence \Se"quence\, v. t. (Biochem.) to determine the sequence of; as, to sequence a protein or a DNA fragment.

late 14c., "hymn sung after the Hallelujah and before the Gospel," from Old French sequence "answering verses" (13c.), from Medieval Latin sequentia "a following, a succession," from Latin sequentem (nominative sequens), present participle of sequi "to follow" (see sequel). In Church use, a partial loan-translation of Greek akolouthia, from akolouthos "following." General sense of "succession," also "a sequence at cards," appeared 1570s.

"arrange in a sequence," 1954, from sequence (n.). Related: Sequenced; sequencing.

n. 1 A set of things next to each other in a set order; a series 2 A series of musical phrases where a theme or melody is repeated, with some change each time, such as in pitch or length (example: opening of Beethoven's ''Fifth Symphony''). 3 A musical composition used in some Catholic Masses between the readings. The most famous sequence is the ''Dies Irae'' (Day of Wrath) formerly used in funeral services. 4 (context mathematics English) An ordered list of objects. 5 (context now rare English) A subsequent event; a consequence or result. 6 A series of shots that depict a single action or style in a film, television show etc. vb. 1 (context transitive English) to arrange in an order 2 (context transitive English) to determine the order of things, especially of amino acids in a protein, or of bases in a nucleic acid 3 (context transitive English) to produce (music) with a sequencer

1. n. serial arrangement in which things follow in logical order or a recurrent pattern; "the sequence of names was alphabetical"; "he invented a technique to determine the sequence of base pairs in DNA"

2. a following of one thing after another in time; "the doctor saw a sequence of patients" [syn: chronological sequence, succession, successiveness, chronological succession]

3. film consisting of a succession of related shots that develop a given subject in a movie [syn: episode]

4. the action of following in order; "he played the trumps in sequence" [syn: succession]

5. several repetitions of a melodic phrase in different keys

1. v. arrange in a sequence

2. determine the order of constituents in; "They sequenced the human genome"

Sequence may refer to any ordered collection of things:

Sequence, a board-and- card game, was invented by Douglas Reuter in Minneapolis, Minnesota, over a two-year period in the 1970s. Mr. Reuter originally called the game, "Sequence Five". Reuter spent years developing the concept, and, in June 1981, granted Jax Ltd. an exclusive license to manufacture, distribute and sell the board game, Sequence, and its subsequent variations. The game was first sold in a retail store in 1982.

A sequence in geology refers to a sequence of geological events, processes, or rocks, arranged in chronological order.

A rock stratigraphical sequence is a geographical, or lithostratigraphic, discrete unit greater than a group or supergroup rank, and traceable over large areas of a continent. A stratigraphic sequence is bounded by unconformities of inter regional scope, such as in the division of cratons.

A sequence in biology is the one-dimensional ordering of monomers, covalently linked within a biopolymer; it is also referred to as the primary structure of the biological macromolecule.

In medicine, a sequence is a series of ordered consequences due to a single cause.

It differs from a syndrome in that seriality is more predictable: if A causes B, and B causes C, and C causes D, then D would not be seen if C is not seen. However, in less formal contexts, the term "syndrome" is sometimes used instead of sequence.

Examples include:

• oligohydramnios sequence (also known as Potter sequence)
• Pierre Robin sequence
• Poland sequence

In mathematics, a sequence is an enumerated collection of objects in which repetitions are allowed. Like a set, it contains members (also called elements, or terms). The number of elements (possibly infinite) is called the length of the sequence. Unlike a set, order matters, and exactly the same elements can appear multiple times at different positions in the sequence. Formally, a sequence can be defined as a function whose domain is either the set of the natural numbers (for infinite sequences) or the set of the first n natural numbers (for a sequence of finite length n). The position of an element in a sequence is its rank or index; it is the integer from which the element is the image; it depends on the context or of a specific convention, if the first element has index 0 or 1. When a symbol has been chosen for denoting a sequence, the nth element of the sequence is denoted by this symbol with n as subscript; for example, the nth element of the Fibonacci sequence is generally denoted F.

For example, (M, A, R, Y) is a sequence of letters with the letter 'M' first and 'Y' last. This sequence differs from (A, R, M, Y). Also, the sequence (1, 1, 2, 3, 5, 8), which contains the number 1 at two different positions, is a valid sequence. Sequences can be finite, as in these examples, or infinite, such as the sequence of all even positive integers (2, 4, 6, ...). In computing and computer science, finite sequences are sometimes called strings, words or lists, the different names commonly corresponding to different ways to represent them in computer memory; infinite sequences are also called streams. The empty sequence ( ) is included in most notions of sequence, but may be excluded depending on the context.

In film, a sequence is a series of scenes that form a distinct narrative unit, which is usually connected either by unity of location or unity of time. For example a heist film might include an extended recruitment sequence in which the leader of the gang collects together the conspirators, a robbery sequence, an escape sequence, and so on. Each of these sequences might further contain sub-sequences; for example the robbery sequence might consist of an entry sequence, a safe-cracking sequence, and so on.

The sequence is one of a hierarchy of structural units used to describe the structure of films in varying degrees of granularity. Analysed this way, a film is composed of one or more acts; acts include one or more sequences; sequences are divided into one or more scenes; and scenes may be thought of as being built out of shots (if one is thinking visually) or beats (if one is thinking in narrative terms).

The sequence paradigm of screenwriting was developed by Frank Daniel.

A sequence ( Latin: sequentia) is a chant or hymn sung or recited during the liturgical celebration of the Eucharist for many Christian denominations, before the proclamation of the Gospel. By the time of the Council of Trent (1543–1563) there were sequences for many feasts in the Church's year.

The sequence has always been sung before the Gospel. The 2002 edition of the General Instruction of the Roman Missal, however, reversed the order and places the sequence before the Alleluia.

The form of this chant inspired a genre of Latin poetry written in a non- classical metre, often on a sacred Christian subject, which is also called a sequence.

In music, a sequence is the restatement of a motif or longer melodic (or harmonic) passage at a higher or lower pitch in the same voice. It is one of the most common and simple methods of elaborating a melody in eighteenth and nineteenth century classical music ( Classical period and Romantic music). Characteristics of sequences:

• Two segments, usually no more than three or four
• Usually only one direction: continuingly higher or lower
• Segments continue by same interval distance

It is possible for melody or harmony to form a sequence without the other participating.

A real sequence is a sequence where the subsequent segments are exact transpositions of the first segment. A tonal sequence is a sequence where the subsequent segments are diatonic transpositions of the first segments. A modified sequence is a sequence where the subsequent segments are decorated or embellished so as to not destroy the character of the original segment. A false sequence is a literal repetition of the beginning of a figure and stating the rest in sequence. A modulating sequence is a sequence that leads from one tonal center to the next, with each segment technically being in a different key in some sequences. A rhythmic sequence is the repetition of a rhythm with free use of pitches.

A sequence can be described according to its direction (ascending or descending in pitch) and its adherence to the diatonic scale—that is, the sequence is diatonic if the pitches remain within the scale, or chromatic (or non-diatonic) if pitches outside of the diatonic scale are used and especially if all pitches are shifted by exactly the same interval (i.e., they are transposed). The non-diatonic sequence tends to modulate to a new tonality or to cause temporarily tonicisation.

At least two instances of a sequential pattern—including the original statement—are required to identify a sequence, and the pattern should be based on several melody notes or at least two successive harmonies ( chords). Although stereotypically associated with Baroque music, and especially the music of Antonio Vivaldi, this device is widespread throughout Western music history.

Ritornellos and the amplification from melodies to Baroque lyrics are often built from sequences.

Sequence was a short-lived but influential British film journal founded in 1947 by Lindsay Anderson, Gavin Lambert and Karel Reisz.

Anderson had returned to Oxford after his time with the army Intelligence Corps in Delhi, Lambert was a schoolfriend of Anderson from Cheltenham College who had dropped out of English at Magdalen College on discovering that he would have to study Middle English under C. S. Lewis, while Reiz was a chemistry graduate from Emmanuel College, Cambridge who later said "I met Lindsay Anderson on a Green Line bus. I was going to the British Film Institute to look at some film for my editing book and he was going to see Ford's The Iron Horse."

Founded as the Film Society Magazine, the organ of the Oxford Film Society, in 1947, with Penelope Houston as its first editor, the journal quickly changed its name to Sequence, and produced fourteen issues between 1947 and 1952, the last few being edited by Reisz and Anderson. The British Free Cinema movement, co-founded in 1956 by Lindsay Anderson, Karel Reisz, Tony Richardson and Lorenza Mazzetti, drew on the principles first expressed by the journal. Articles from Sequence by Anderson were published in Lindsay Anderson: The Collected Writings edited by Paul Ryan (London: Plexus, 2004).

Sequence is a 2013 short fantasy horror film written and directed by Carles Torrens, and starring Joe Hursley, Emma Fitzpatrick, and Ronnie Gene Blevins. The film premiered September 6, 2013, at the Los Angeles International Short Film Festival.
