Chord Progression
In a musical composition, a chord progression or harmonic progression (informally chord changes, used as a plural, or simply changes) is a succession of chords. Chord progressions are the foundation of harmony in Western musical tradition from the common practice era of Classical music to the 21st century. Chord progressions are the foundation of popular music styles (e.g., pop music, rock music), traditional music, as well as genres such as blues and jazz. In these genres, chord progressions are the defining feature on which melody and rhythm are built. In tonal music, chord progressions have the function of either establishing or otherwise contradicting a tonality, the technical name for what is commonly understood as the " key" of a song or piece. Chord progressions, such as the extremely common chord progression I-V-vi-IV, are usually expressed by Roman numerals in Classical music theory. In many styles of popular and traditional music, chord progressions are expressed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Arithmetic Progression
An arithmetic progression or arithmetic sequence is a sequence of numbers such that the difference from any succeeding term to its preceding term remains constant throughout the sequence. The constant difference is called common difference of that arithmetic progression. For instance, the sequence 5, 7, 9, 11, 13, 15, . . . is an arithmetic progression with a common difference of 2. If the initial term of an arithmetic progression is a_1 and the common difference of successive members is d, then the n-th term of the sequence (a_n) is given by :a_n = a_1 + (n - 1)d. A finite portion of an arithmetic progression is called a finite arithmetic progression and sometimes just called an arithmetic progression. The sum of a finite arithmetic progression is called an arithmetic series. History According to an anecdote of uncertain reliability, in primary school Carl Friedrich Gauss reinvented the formula \tfrac for summing the integers from 1 through n, for the case n=100, by grouping t ...

Ragtime Progression
The ragtime progression is a chord progression characterized by a chain of secondary dominants following the circle of fifths, named for its popularity in the ragtime genre, despite being much older. Also typical of parlour music, its use originated in European classical music, classical music and later spread to American folk music. Growing, "by a process of gradual accretion. First the dominant (music), dominant chord acquired its own dominant...This then acquired ''its'' dominant, which in turn acquired yet another dominant, giving":Van der Merwe (2005), p.299. It can be represented in Roman numeral analysis as : or : In C major this is : Most commonly found in its four-chord version (including the chord in parentheses). This may be perceived as a, "harder, bouncier sounding progression," than the diatonic vi–ii–V7–I (in C: Am–Dm–G7–C).Scott, Richard J. (2003).

Geometric Progression
A geometric progression, also known as a geometric sequence, is a mathematical sequence of non-zero numbers where each term after the first is found by multiplying the previous one by a fixed number called the ''common ratio''. For example, the sequence 2, 6, 18, 54, ... is a geometric progression with a common ratio of 3. Similarly 10, 5, 2.5, 1.25, ... is a geometric sequence with a common ratio of 1/2. Examples of a geometric sequence are powers ''r''''k'' of a fixed non-zero number ''r'', such as 2''k'' and 3''k''. The general form of a geometric sequence is :a,\ ar,\ ar^2,\ ar^3,\ ar^4,\ \ldots where ''r'' is the common ratio and ''a'' is the initial value. The sum of a geometric progression's terms is called a '' geometric series''. Properties The ''n''th term of a geometric sequence with initial value ''a'' = ''a''1 and common ratio ''r'' is given by :a_n = a\,r^, and in general :a_n = a_m\,r^. Geometric sequences satisfy the linear recurrence relation :a_n = r\,a_ f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Harmonic Progression (mathematics)
In mathematics, a harmonic progression (or harmonic sequence) is a progression formed by taking the reciprocals of an arithmetic progression, which is also known as an arithmetic sequence. Equivalently, a sequence is a harmonic progression when each term is the harmonic mean of the neighboring terms. As a third equivalent characterization, it is an infinite sequence of the form : \frac,\ \frac,\ \frac,\ \frac, \cdots, where ''a'' is not zero and −''a''/''d'' is not a natural number, or a finite sequence of the form : \frac,\ \frac,\ \frac,\ \frac, \cdots,\ \frac, where ''a'' is not zero, ''k'' is a natural number and −''a''/''d'' is not a natural number or is greater than ''k''. Examples In the following is a natural number, in sequence: \ n = 1,\ 2,\ 3,\ 4,\ \ldots\ * 1, \tfrac,\ \tfrac,\ \tfrac,\ \tfrac,\ \tfrac,\ \ldots \ , \ \tfrac,\ \ldots \ is called the ''harmonic sequence'' * 12, 6, 4, 3, \ \tfrac,\ 2,\ \ldots\ ,\ \tfrac,\ \ldots\ * 30, −30, −10, −6 ...

Omnibus Progression
The omnibus progression in music is a chord progression characterized by chromatic lines moving in opposite directions. The progression has its origins in the various Baroque harmonizations of the descending chromatic fourth in the bass ostinato pattern of passacaglia, known as the "lament bass". However, in its fullest form the omnibus progression involves a descent in the bass which traverses a whole octave and includes every note of the chromatic scale. It may also include one or more chromatic ascending tetrachords in the soprano, tenor and alto. They are also known as "chromatic wedge progressions", in reference to their wedge-like appearance in score. Gauldin, Robert. "The Theory and Practice of Chromatic Wedge Progressions in Romantic Music." ''Music Theory Spectrum'', vol. 26, no. 1. (Spring 2004), pp. 1–22. The origin of the term "omnibus" (Latin: "for all") to describe such a sequence is unclear, but it is of note that the chord progression encompasses ''all'' of the no ...

Backdoor Progression
In jazz and jazz harmony, the chord progression from iv7 to VII7 to I (the tonic or "home" chord) has been nicknamed the backdoor progressionCoker, Jerry (1997). ''Elements of the Jazz Language for the Developing Improvisor'', p.82. . "Back Door Progression As A Substitute For V7 The I chord, in a given progression, is often preceded by IV-7 to VII7, ''instead of the usual V7 chord''.". or the backdoor ii-V, as described by jazz theorist and author Jerry Coker. This name derives from an assumption that the normal progression to the tonic, the ii-V-I turnaround (ii-V7 to I, see also authentic cadence) is, by inference, the "front door", a metaphor suggesting that this is the main route to the tonic. The VII7 chord, a pivot chord borrowed from the parallel minor of the current tonic major key, is a dominant seventh. Therefore, it can resolve to I; it is commonly preceded by IV going to iv, then VII7, then I. In C major the dominant would be G7: (the notes GBDF), sharing two ...

Astrological Progression
Astrological progressions are one of the main means used in Horoscopic astrology to forecast future trends and developments (the other means is transits, which are simply the ongoing movements of the planets across the sky). As its name implies, astrological progression involves a method of ''progressing'' the Horoscope forward from the moment of the birth or beginning of the subject into the future, and is most usually done for the birth or natal chart of a particular individual. There are two main forms of progression: ''Secondary progression'' or 'a-day-for-a-year' progression; and ''Solar arc direction'' or 'a-degree-for-a-year' progression. In both systems, the planets, Ascendant, and Midheaven are all seen to have changed position in the progressed chart, and these changes are noted. Particular attention is paid to changes of zodiac signs and houses, and to the angles or aspects the progressed planets form with the original natal chart. Predictive astrology Astrological ...

Educational Stage
Educational stages are subdivisions of formal learning, typically covering early childhood education, primary education, secondary education and tertiary education. The United Nations Educational, Scientific and Cultural Organization (UNESCO) recognizes nine levels of education in its International Standard Classification of Education (ISCED) system (from Level 0 (pre-primary education) through Level 8 (doctoral)). UNESCO's International Bureau of Education maintains a database of country-specific education systems and their stages. Some countries divide levels of study into grades or forms for school children in the same year. Organization Education during childhood and early adulthood is typically provided through either a two- or three-stage system of childhood school, followed by additional stages of higher education or vocational education for those who continue their formal education: *Early childhood education at preschool, nursery school, or kindergarten (outside the U. ...
