Descending Tetrachord
In music theory, the descending tetrachord is a series of four notes from a scale, or tetrachord, arranged in order from highest to lowest, or descending order. For example, --- , as created by the Andalusian cadence. The descending tetrachord may fill a perfect fourth or a chromatic fourth.

Music Theory
Music theory is the study of the practices and possibilities of music. ''The Oxford Companion to Music'' describes three interrelated uses of the term "music theory". The first is the "rudiments", that are needed to understand music notation (key signatures, time signatures, and rhythmic notation); the second is learning scholars' views on music from antiquity to the present; the third is a sub-topic of musicology that "seeks to define processes and general principles in music". The musicological approach to theory differs from music analysis "in that it takes as its starting-point not the individual work or performance but the fundamental materials from which it is built." Music theory is frequently concerned with describing how musicians and composers make music, including tuning systems and composition methods among other topics. Because of the ever-expanding conception of what constitutes music, a more inclusive definition could be the consideration of any sonic phenomena, ...

Scale (music)
In music theory, a scale is any set of musical notes ordered by fundamental frequency or pitch. A scale ordered by increasing pitch is an ascending scale, and a scale ordered by decreasing pitch is a descending scale. Often, especially in the context of the common practice period, most or all of the melody and harmony of a musical work is built using the notes of a single scale, which can be conveniently represented on a staff with a standard key signature. Due to the principle of octave equivalence, scales are generally considered to span a single octave, with higher or lower octaves simply repeating the pattern. A musical scale represents a division of the octave space into a certain number of scale steps, a scale step being the recognizable distance (or interval) between two successive notes of the scale. However, there is no need for scale steps to be equal within any scale and, particularly as demonstrated by microtonal music, there is no limit to how many notes can ...

Tetrachord
In music theory, a tetrachord ( el, τετράχορδoν; lat, tetrachordum) is a series of four notes separated by three intervals. In traditional music theory, a tetrachord always spanned the interval of a perfect fourth, a 4:3 frequency proportion (approx. 498 cents)—but in modern use it means any four-note segment of a scale or tone row, not necessarily related to a particular tuning system. History The name comes from ''tetra'' (from Greek—"four of something") and ''chord'' (from Greek ''chordon''—"string" or "note"). In ancient Greek music theory, ''tetrachord'' signified a segment of the greater and lesser perfect systems bounded by ''immovable'' notes ( ); the notes between these were ''movable'' ( ). It literally means ''four strings'', originally in reference to harp-like instruments such as the lyre or the kithara, with the implicit understanding that the four strings produced adjacent (i.e., conjunct) notes. Modern music theory uses the octave as the basic u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Andalusian Cadence
The Andalusian cadence (diatonic phrygian tetrachord) is a term adopted from flamenco music for a chord progression comprising four chords descending stepwise – a iv–III–II–I progression with respect to the Phrygian mode or i–VII–VI–V progression with respect to the Aeolian mode(minor).Mojácar Flamenco , a website about basics in Flamenco music It is otherwise known as the minor descending tetrachord. Traceable back to the , its effective sonorities made it one of the most popular progressions in |
Perfect Fourth
A fourth is a musical interval encompassing four staff positions in the music notation of Western culture, and a perfect fourth () is the fourth spanning five semitones (half steps, or half tones). For example, the ascending interval from C to the next F is a perfect fourth, because the note F is the fifth semitone above C, and there are four staff positions between C and F. Diminished and augmented fourths span the same number of staff positions, but consist of a different number of semitones (four and six, respectively). The perfect fourth may be derived from the harmonic series as the interval between the third and fourth harmonics. The term ''perfect'' identifies this interval as belonging to the group of perfect intervals, so called because they are neither major nor minor. A perfect fourth in just intonation corresponds to a pitch ratio of 4:3, or about 498 cents (), while in equal temperament a perfect fourth is equal to five semitones, or 500 cents (see additive s ...

Chromatic Fourth
In music theory, a chromatic fourth, or ''passus duriusculus'',Monelle, Raymond (2000). ''The Sense of Music: Semiotic Essays'', p.73. . is a melody or melodic fragment spanning a perfect fourth with all or almost all chromatic intervals filled in ( chromatic line). The quintessential example is in D minor with the tonic and dominant notes as boundaries: \relative c The chromatic fourth was first used in the madrigals of the 16th Century. The Latin term itself—"harsh" or "difficult" (''duriusculus'') "step" or "passage" (''passus'')—originates in Christoph Bernhard's 17th century ''Tractatus compositionis augmentatus'' (1648–49), where it appears to refer to repeated melodic motion by semitone creating consecutive semitones. The term may also relate to the ''pianto'' associated with weeping. In the Baroque, Johann Sebastian Bach used it in his choral as well as his instrumental music, in the ''Well-Tempered Clavier'', for example (the chromatic fourth is indicated by ...

Chaconne
A chaconne (; ; es, chacona, links=no; it, ciaccona, links=no, ; earlier English: ''chacony'') is a type of musical composition often used as a vehicle for variation on a repeated short harmonic progression, often involving a fairly short repetitive bass-line (ground bass) which offers a compositional outline for variation, decoration, figuration and melodic invention. In this it closely resembles the passacaglia. It originates and was particularly popular in the Baroque era; a large number of Chaconnes exist from the 17th- and 18th- centuries. The ground bass, if there is one, may typically descend stepwise from the tonic to the dominant pitch of the scale; the harmonies given to the upper parts may emphasize the circle of fifths or a derivative pattern thereof. History Though it originally emerged during the late sixteenth century in Spanish culture, having reputedly been introduced from the New World, as a quick dance-song characterized by suggestive movements and mo ...

Lament Bass
In music, the lament bass is a ground bass, built from a descending perfect fourth from tonic to dominant, with each step harmonized.Brover-Lubovsky, Bella (2008). ''Tonal Space in the Music of Antonio Vivaldi'', p.151-52. . The diatonic version is the upper tetrachord from the natural minor scale, known as the Phrygian tetrachord, while the chromatic version, the chromatic fourth, has all semitones filled in. It is often used in music to denote tragedy or sorrow. However, "A common misperception exists that the 'lament bass' of Venetian opera became so prevalent that it immediately swept away all other possible affective associations with this bass pattern...To cite but one example, Peter Holman, writing about Henry Purcell, once characterized the minor tetrachord as 'the descending ground that was associated with love in seventeenth-century opera'."
