In music theory, the Andalusian cadence is a chord progression commonly found in Flamenco music. It is designated as a (iv - III- II - I) progression. Since much of the music is played in two keys, each is now called by its own distinctive name. One is por arriba, played in the key of E, comprises of the following chord progression (Am - G - F - E) and por medio, played in the key of A, with (Dm - C - Bb - A). ...more on Wikipedia about "Andalusian cadence"

"Gino Stefani makes appropriation the chief criterion for his 'popular' definition of melody (Stefani 1987a). Melody, he argues, is music 'at hand'; it is that dimension which the common musical competence extracts (often with little respect for the integrity of the source), appropriates and uses for a variety of purposes: singing, whistling, dancing, and so on." (Middleton, p.96) ...more on Wikipedia about "Appropriation (music)"

In music and music theory augmentation is the lengthening or widening of rhythms, melodies, intervals, chords. The opposite is diminution (diminished). ...more on Wikipedia about "Augmentation (music)"

In music the axis system, proposed by Ernő Lendvai (1971, p.1-16) in his analysis of the use of tonality in the music of Béla Bartók, is an assignment of harmonic function to all twelve pitch classes in relation to an assigned tonic, determined by that pitch classes interval from the tonic. The three functions used are tonic, subdominant, and dominant and each contains four notes (forming three diminished seventh chords). Each group is then divided into principal and secondary groups a tritone apart and thus there are six pairs of notes in three categories. ...more on Wikipedia about "Axis system"

In music, the BACH motif is the sequence of notes B flat, A, C, B natural. ...more on Wikipedia about "BACH motif"

In music and music theory, chord multiplication is a process whereby new pitch sets are generated by overlaying and transposing the pitch classes of one chord onto the pitch classes of another. ...more on Wikipedia about "Chord multiplication"

In music, chordal space is a mathematical model of relationships between chords in some musical system. These models are often graphs, or tilings. Closely related to chordal space is modulatory space, which represents pitch classes; the chords of a chordal space are chosen from the pitch classes of a modulatory space. ...more on Wikipedia about "Chordal space"

In music, a consonance (Latin consonare, "sounding together") is a harmony, chord, or interval considered stable, as opposed to a dissonance, which is considered unstable. The strictest definition of consonance may be only those sounds which are pleasant, while the most general definition includes any sounds which are used freely. ...more on Wikipedia about "Consonance and dissonance"

A diatonic function, in tonal music theory, is the specific, recognized roles of notes or chords in relation to the key. ...more on Wikipedia about "Diatonic function"

In the theory of byzantine music echos is the concept most akin to that of mode or maqam. ...more on Wikipedia about "Echos"

Harmolodics is a music theory developed by jazz saxophonist Ornette Coleman. Associated primarily with the jazz avant-garde and the free jazz movement, harmolodics seeks to free musical compositions from any tonal centre, allowing harmonic progression independent of traditional European notions of tension and release. ...more on Wikipedia about "Harmolodics"

Harmony is the use and study of pitch simultaneity and chords, actual or implied, in music. It is sometimes referred to as the "vertical" aspect of music, with melody being the "horizontal" aspect. Very often, harmony is a result of counterpoint or polyphony, several melodic lines or motifs being played at once, though harmony may control the counterpoint. ...more on Wikipedia about "Harmony"

Imitation. In its broadest sense, repetition of the melodic contour of one part by another, often at a different pitch. Usually, in a passage referred to as 'imitative', the repeated passages are close enough together for the second part to overlap with significant material in the first, although the term is sometimes used to desribe echoing or dialoguelike repetitions among parts (such as those between woodwind and strings in Mozart's Symphony in G minor K550, first movement, bars 153-64) or examples of voice-exchange. When the material of the succeeding voice follows exactly that of the preceding one for a considerable time, the term 'canon' is used; when an entire piece is based on the imitation of a single, fairly concise theme in a strongly tonal context, the terms 'fugue' or 'fugato' may be used. The term 'imitation' is now normally reserved for fairly casual instances of the device, particularly in works of an otherwise non-contrapuntal nature(Cusick, Suzanne G. Italic textImitationItalic text. The New Grove Encyclopedia of Music and Musicians. Edited by Stanley Sadie. Second edition, vol. 12). ...more on Wikipedia about "Imitation (music)" This text is made on shortopedia

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. ...more on Wikipedia about "Inversion (music)"

Jazz Harmony is a highly sophisticated harmonic idiom that incorporates traditional harmony as well as non-traditional techniques. ...more on Wikipedia about "Jazz harmony"

Low C is the note C that is one octave below Middle C, and is also named C3. It is named because it is considered the low note of the voice (only the baritones and basses go much lower). It is the low note of the tenor in classical music. ...more on Wikipedia about "Low C"

Mensural notation is the musical notation system which was used from the later part of the 13th century until about 1600. ...more on Wikipedia about "Mensural notation"

In music, modulatory space is a mathematical model of relationships between pitch classes in some musical system. These models are often graphs, groups or lattices. Closely related to modulatory space is pitch space, which represents pitches rather than pitch classes, and chordal space, which models relationships between chords. ...more on Wikipedia about "Modulatory space"

In music and musical set theory, multiplication modulo 12 is a basic operation which may be performed on pitch or pitch class sets. Dealing with all twelve tones, or a tone row, there are only a few numbers which one may multiply a row by and still end up with twelve tones. Taking the prime or unaltered form as P0, multiplication is indicated by Mx, x being the multiplicator: ...more on Wikipedia about "Multiplication (music)"

A museme is a minimal unit of musical meaning, analgous to a morpheme in linguistics, "the basic unit of musical expression which in the framework of one given musical system is not further divisible without destruction of meaning." A museme may: ...more on Wikipedia about "Museme"

A current viewpoint indicates that tonal scales and tonality arise from overtones, and can be found at in the 2004 book: "On the Origin of Music" by Bob Fink (Greenwich Publ., Canada). The theory is called the "trio theory," claiming that influence from the most audible overtones of the three most nearly universal intervals (found across time and cultures), namely, a tone's octave, 4th and 5th, when placed within the range of that octave, will evolve into the most widespread of scales: Pentatonic, major and minor (depending how many of the audible overtones are so placed). The unequal audibile strengths of the overtones determine the role and power of each note in a scale ( tonic, dominant or subdominant) -- i.e., tonality and tonal scales. ...more on Wikipedia about "Music (history of scale)"

Music theory is a field of study that describes the elements of music and includes the development and application of methods for analyzing and composing music, and the interrelationship between the notation of music and performance practice. Broadly, theory may include any statement, belief, or conception of music ( Boretz, 1995). A person who studies or practices music theory is a music theorist. ...more on Wikipedia about "Music theory"

Nenano is the name of the one of the two "extra" modes in the Byzantine Octoechos, that is the modal system of the eastern roman chant. The second "extra mode" is named nana. These two modes were later identified with phthorai, that signs indicating specific modulation or alteration phenomena (see more below). ...more on Wikipedia about "Nenano"

Octoechos ("8 echos") is the fundamental structure for classifying and describing modes in byzantine music. ...more on Wikipedia about "Octoechos"
