Pitch classIn music, a pitch class (p.c. or pc) is a set of all pitches that are a whole number of octaves apart; for example, the pitch class C consists of the Cs in all octaves. "The pitch class C stands for all possible Cs, in whatever octave position." Important to musical set theory, a pitch class is "all pitches related to each other by octave, enharmonic equivalence, or both." Thus, using scientific pitch notation, the pitch class "C" is the set {Cn : n is an integer} = {..., C−2, C−1, C0, C1, C2, C3 ...}.
Music historyMusic history, sometimes called historical musicology, is a highly diverse subfield of the broader discipline of musicology that studies music from a historical point of view. In theory, "music history" could refer to the study of the history of any type or genre of music (e.g., the history of Indian music or the history of rock). In practice, these research topics are often categorized as part of ethnomusicology or cultural studies, whether or not they are ethnographically based.
Analyse musicaleL’analyse musicale est une discipline consistant en l'étude d'une œuvre musicale de façon à en comprendre la genèse, l'architecture et les dessins. Après avoir déterminé le contexte historique, culturel et stylistique de la composition, s'être penché sur la biographie, les influences de l'auteur et les circonstances de la création, une analyse musicale examinera le genre, la forme, la structure, les indications de mouvement et de tempo (leurs agogiques éventuelles), les tonalités, les enchaînements harmoniques, les formules cadentielles et l'orchestration sans oublier l'observation minutieuse de la mélodie, des différentes voix polyphoniques, du rythme, des nuances et de la dynamique et des ornementations.
Accord parfait mineurEn musique, l’accord parfait mineur est composé d'une fondamentale, d'une tierce mineure et d'une quinte juste (c'est-à-dire une tierce majeure superposée à tierce mineure). Par exemple : do, mib, sol (accord parfait de do mineur) : \new Staff \with {\remove "Time_signature_engraver"}{\time 4/4
Minor scaleIn music theory, the minor scale is three scale patterns – the natural minor scale (or Aeolian mode), the harmonic minor scale, and the melodic minor scale (ascending or descending) – mirroring the major scale, with its harmonic and melodic forms In each of these scales, the first, third, and fifth scale degrees form a minor triad (rather than a major triad, as in a major scale). In some contexts, minor scale is used to refer to any heptatonic scale with this property (see Related modes below).
Analyse harmonique (mathématiques)thumb|upright=1.2|Analyseur harmonique mécanique de Lord Kelvin datant de 1878. L'analyse harmonique est la branche des mathématiques qui étudie la représentation des fonctions ou des signaux comme superposition d'ondes de base. Elle approfondit et généralise les notions de série de Fourier et de transformée de Fourier. Les ondes de base s'appellent les harmoniques, d'où le nom de la discipline.
Guitar chordIn music, a guitar chord is a set of notes played on a guitar. A chord's notes are often played simultaneously, but they can be played sequentially in an arpeggio. The implementation of guitar chords depends on the guitar tuning. Most guitars used in popular music have six strings with the "standard" tuning of the Spanish classical guitar, namely E–A–D–G–B–E' (from the lowest pitched string to the highest); in standard tuning, the intervals present among adjacent strings are perfect fourths except for the major third (G,B).
Cognitive musicologyCognitive musicology is a branch of cognitive science concerned with computationally modeling musical knowledge with the goal of understanding both music and cognition. Cognitive musicology can be differentiated from other branches of music psychology via its methodological emphasis, using computer modeling to study music-related knowledge representation with roots in artificial intelligence and cognitive science. The use of computer models provides an exacting, interactive medium in which to formulate and test theories.
AnalysisAnalysis (: analyses) is the process of breaking a complex topic or substance into smaller parts in order to gain a better understanding of it. The technique has been applied in the study of mathematics and logic since before Aristotle (384–322 B.C.), though analysis as a formal concept is a relatively recent development. The word comes from the Ancient Greek ἀνάλυσις (analysis, "a breaking-up" or "an untying;" from ana- "up, throughout" and lysis "a loosening"). From it also comes the word's plural, analyses.
Minor seventh chordIn music, a minor seventh chord is a seventh chord composed of a root note, together with a minor third, a perfect fifth, and a minor seventh (1, 3, 5, 7). For example, the minor seventh chord built on C, commonly written as C–7, has pitches C–E–G–B: { \new Staff \with{ \magnifyStaff #1.5 } \relative c' { \override Score.TimeSignature #'stencil = ##f 1 } } A seventh chord with a minor third, perfect fifth, and minor seventh is commonly called a minor seventh chord, but also sometimes a minor/minor seventh chord to distinguish it from the minor/major seventh chord discussed below.
