He Development of Harmony Is Central in Western Art Music
Introduction
Barbershop quartets, such equally this U.S. Navy group, sing iv-part pieces, made up of a melody line (normally the lead) and 3 harmony parts.When you lot have more than ane pitch sounding at the same time in music, the result is harmony. Harmony is one of the bones elements of music, only information technology is non every bit bones as some other elements, such as rhythm and melody. You can accept music that is but rhythms, with no pitches at all. You can too have music that is but a unmarried melody, or just a melody with rhythm accessory.
Harmony is two or more notes played together at the same fourth dimension. As presently as there is more than than one pitch sounding at a time, you accept harmony. Even if nobody is really playing chords, or even if the notes are part of independent contrapuntal lines, y'all can hear the relationship of any notes that happen at the aforementioned fourth dimension, and it is this relationship that makes the harmony.
Note: Harmony does not take to be peculiarly "harmonious"; it may be quite dissonant, in fact. For the purpose of definitions, the of import fact is the notes sounding at the same time.
Harmony is the well-nigh emphasized and most highly developed element in Western music, and can be the subject area of an entire course on music theory.
In music, harmony is the use of simultaneous pitches (tones, notes), or chords. The report of harmony involves chords and their structure and chord progressions and the principles of connectedness that govern them. Harmony is often said to refer to the "vertical" aspect of music, as distinguished from melodic line, or the "horizontal" aspect.
In many types of music, notably baroque, romantic, modern and jazz, chords are often augmented with "tensions". A tension is an additional chord member that creates a relatively dissonant interval in relation to the bass. Typically, in the classical common exercise menstruum a anomalous chord (chord with tension) "resolves" to a consonant chord. Harmonization commonly sounds pleasant to the ear when there is a balance betwixt the consonant and anomalous sounds. In simple words, that occurs when at that place is a balance between "tense" and "relaxed" moments.
Etymology and Definitions
The term harmony derives from the Greek ἁρμονία (harmonía), significant "joint, understanding, agree", from the verb ἁρμόζω (harmozo), "to fit together, to join". In Ancient Hellenic republic, the term defined the combination of assorted elements: a higher and lower note.
Rameau's 'Traité de 50'harmonie' (Treatise on Harmony) from 172
It was non until the publication of Rameau'south "Traité de 50'harmonie" (Treatise on Harmony) in 1722 that whatsoever text discussing musical practice fabricated use of the term in the championship, though that work is not the earliest record of theoretical discussion of the topic. The underlying principle backside these texts is that harmony sanctions harmoniousness (sounds that 'please') past conforming to sure pre-established compositional principles.
The view that modern tonal harmony in Western music began in about 1600 is commonplace in music theory. This is usually deemed for by the 'replacement' of horizontal (of contrapuntal) writing, common in the music of the Renaissance, with a new emphasis on the 'vertical' element of composed music. Modern theorists, nevertheless, tend to see this every bit an unsatisfactory generalisation. As Carl Dahlhaus puts it,
It was not that counterpoint was supplanted by harmony (Bach'south tonal counterpoint is surely no less polyphonic than Palestrina'due south modal writing) but that an older blazon both of counterpoint and of vertical technique was succeeded past a newer type. And harmony comprises not only the ('vertical') structure of chords merely also their ('horizontal') motion. Like music as a whole, harmony is a process.
Descriptions and definitions of harmony and harmonic practise may testify bias towards European (or Western) musical traditions. For example, S Asian fine art music (Hindustani and Carnatic music) is frequently cited as placing little emphasis on what is perceived in western exercise equally conventional 'harmony'; the underlying 'harmonic' foundation for most Southward Asian music is the drone, a held open up fifth (or quaternary) that does not alter in pitch throughout the course of a composition.
Nevertheless, emphasis on the precomposed in European art music and the written theory surrounding it shows considerable cultural bias. The Grove Lexicon of Music and Musicians (Oxford Academy Press) identifies this clearly:
In Western civilization the musics that are about dependent on improvisation, such every bit jazz, accept traditionally been regarded as inferior to art music, in which pre-composition is considered paramount. The conception of musics that live in oral traditions as something composed with the use of improvisatory techniques separates them from the higher-continuing works that use annotation.
Still the evolution of harmonic practice and language itself, in Western art music, is and was facilitated by this process of prior composition (which permitted the written report and analysis by theorists and composers alike of individual pre-constructed works in which pitches—and to some extent rhythms—remained unchanged regardless of the nature of the performance).
Historical Rules
Some traditions of Western music performance, composition, and theory accept specific rules of harmony. These rules are often described as based on natural properties such equally Pythagorean tuning's law whole number ratios ("harmoniousness" beingness inherent in the ratios either perceptually or in themselves) or harmonics and resonances ("harmoniousness" being inherent in the quality of sound), with the commanded pitches and harmonies gaining their beauty or simplicity from their closeness to those properties. This model provides that the minor seventh and ninth are not dissonant (i.e., are consonant). While Pythagorean ratios can provide a crude approximation of perceptual harmonicity, they cannot account for cultural factors.
Early Western religious music frequently features parallel perfect intervals; these intervals would preserve the clarity of the original plainsong. These works were created and performed in cathedrals, and made utilize of the resonant modes of their respective cathedrals to create harmonies. As polyphony adult, however, the use of parallel intervals was slowly replaced by the English way of consonance that used thirds and sixths. The English manner was considered to have a sweeter sound, and was amend suited to polyphony in that it offered greater linear flexibility in office-writing. Early music likewise forbade usage of the tritone, every bit its dissonance was associated with the devil, and composers frequently went to considerable lengths, via musica ficta, to avoid using it. In the newer triadic harmonic system, however, the tritone became permissible, as the standardization of functional noise made its apply in ascendant chords desirable.
Most harmony comes from two or more than notes sounding simultaneously—but a work tin can imply harmony with only ane melodic line by using arpeggios or hocket. Many pieces from the baroqueperiod for solo string instruments—such equally Bach's Sonatas and partitas for solo violin and cello—convey subtle harmony through inference rather than full chordal structures. These works create a sense of harmonies past using arpeggiated chords and implied basslines. The implied basslines are created with low notes of brusque duration that many listeners perceive as existence the bass notation of a chord. (See below):

Types
Close position C major triad.
Open position C major triad.
Carl Dahlhaus (1990) distinguishes between coordinate and subordinate harmony. Subordinate harmony is the hierarchical tonality or tonal harmony well known today. Coordinate harmony is the older Medieval and Renaissance tonalité ancienne, "The term is meant to signify that sonorities are linked ane after the other without giving rise to the impression of a goal-directed evolution. A offset chord forms a 'progression' with a 2d chord, and a second with a third. But the former chord progression is independent of the later one and vice versa." Coordinate harmony follows direct (side by side) relationships rather than indirect as in subordinate. Interval cycles create symmetrical harmonies, which accept been extensively used past the composers Alban Berg, George Perle, Arnold Schoenberg, Béla Bartók, and Edgard Varèse'south Density 21.v.
Close harmony and open harmony use close position and open position chords, respectively.
Other types of harmony are based upon the intervals of the chords used in that harmony. Most chords used in western music are based on "tertian" harmony, or chords congenital with the interval of thirds. In the chord C Major7, C-E is a major tertiary; E-Yard is a minor third; and Thousand to B is a major third. Other types of harmony consist of quartal harmony and quintal harmony.
Unison is considered a harmonic interval, just like a fifth or a third. What's unique about unison is that it is two identical notes being played or sung together. Near people only consider thirds and fifths and sevenths to be "harmony". But, unison does count as harmony, and is very of import in orchestration, peculiarly. In Popular music, unison singing is ordinarily chosen "doubling" which is what The Beatles used to do a lot in their early music. Equally a type of harmony, singing in unison or playing the aforementioned notes, often using different musical instruments, at the same time is commonly called monophonic harmonization.
