Barbershop quartets, such as this U.S. Marine group, song 4-part pieces, made up of a melody line (normally the lead) and also 3 harmony parts.When friend have an ext than one key sounding at the very same time in music, the an outcome is harmony. Harmony is one of the straightforward elements the music, however it is not as straightforward as some various other elements, such as rhythm and melody. You can have music that is simply rhythms, through no pitches at all. Friend can additionally have music the is just a single melody, or simply a melody with rhythm accompaniment.

You are watching: Consonant harmonies usually provide a feeling of tension

Harmony is two or more notes played together at the exact same time. As soon as there is an ext than one pitch sounding in ~ a time, you have harmony. Even if nobody is actually play chords, or also if the notes are part of elevation contrapuntal lines, you deserve to hear the connection of any type of notes that occur at the same time, and it is this relationship that provides the harmony.

Note: Harmony does not need to be an especially “harmonious”; it may be quite dissonant, in fact. For the function of definitions, the essential fact is the notes sounding in ~ the exact same time.Harmony is the many emphasized and also most highly occurred element in west music, and also can be the subject of whole course top top music theory.

In music, harmony is the usage of simultaneously pitches (tones, notes), or chords. The examine of harmony involves chords and their construction and also chord progressions and the principles of link that administrate them. Harmony is frequently said to describe the “vertical” facet of music, as distinguished from melodic line, or the “horizontal” aspect. 

In many types of music, especially baroque, romantic, modern-day and jazz, chords are often augmented with “tensions”. A stress and anxiety is an additional chord member that creates a reasonably dissonant expression in relationship to the bass. Typically, in the classic common practice duration a dissonant chord (chord through tension) “resolves” to a consonant chord. Harmonization generally sounds pleasant to the ear as soon as there is a balance between the consonant and dissonant sounds. In simple words, that occurs as soon as there is a balance in between “tense” and “relaxed” moments.

Etymology and Definitions

The ax harmony derives from the Greek ἁρμονία (harmonía), definition “joint, agreement, concord”, from the verb ἁρμόζω (harmozo), “to fit together, to join”. In ancient Greece, the term characterized the combination of contrasted elements: a higher and lower note. 


Rameau’s ‘Traité de l’harmonie’ (Treatise top top Harmony) indigenous 172

The see that modern tonal harmony in west music started in around 1600 is commonplace in music theory. This is usually accounted because that by the ‘replacement’ of horizontal (of contrapuntal) writing, usual in the music of the Renaissance, v a new emphasis ~ above the ‘vertical’ facet of created music. Modern theorists, however, have tendency to watch this as an unsatisfactory generalisation. As Carl Dahlhaus put it,

It was not that counterpoint was supplanted through harmony (Bach’s tonal counterpoint is for sure no much less polyphonic 보다 Palestrina’s modal writing) but that one older form both the counterpoint and also of vertical method was prospered by a newer type. And harmony comprises not just the (‘vertical’) framework of chords but also their (‘horizontal’) movement. Prefer music as a whole, harmony is a process.

Descriptions and also definitions that harmony and harmonic practice may show prejudice towards europe (or Western) musical traditions. For example, South asian art music (Hindustani and also Carnatic music) is generally cited as placing little emphasis top top what is perceived in western exercise as standard ‘harmony’; the underlying ‘harmonic’ foundation for most South oriental music is the drone, a held open 5th (or fourth) that does not transform in pitch throughout the food of a composition. 

Nevertheless, emphasis on the precomposed in European art music and the created theory surrounding it shows considerable cultural bias. The Grove dictionary of Music and Musicians (Oxford university Press) identifies this clearly:

In Western culture the musics that are many dependent top top improvisation, such together jazz, have actually traditionally been concerned as worse to arts music, in which pre-composition is thought about paramount. The conception of musics that live in oral traditions as something composed through the usage of improvisatory methods separates them from the higher-standing functions that usage notation.

Yet the development of harmonic practice and also language itself, in Western arts music, is and was assisted in by this process of prior ingredient (which permitted the research and evaluation by theorists and composers alike of individual pre-constructed works in which pitches—and come some degree rhythms—remained unchanged regardless that the nature that the performance).

Historical Rules

Some legacies of west music performance, composition, and also theory have details rules that harmony. This rules room often explained as based on natural properties such together Pythagorean tuning’s law entirety number ratios (“harmoniousness” being natural in the ratios one of two people perceptually or in themselves) or harmonics and also resonances (“harmoniousness” being innate in the top quality of sound), through the allowable pitches and harmonies gaining their beauty beauty or simplicity from your closeness come those properties. This model offers that the young seventh and also ninth room not dissonant (i.e., room consonant). While Pythagorean ratios can administer a rough approximation of perceptual harmonicity, they cannot account for social factors.

Early Western religious music often features parallel perfect intervals; this intervals would preserve the clarity of the original plainsong. These works were created and performed in cathedrals, and also made use of the resonant settings of your respective cathedrals to create harmonies. Together polyphony developed, however, the use of parallel intervals was slowly replaced by the English style of consonance that offered thirds and also sixths. The English style was considered to have a sweeter sound, and also was better suited to polyphony in the it available greater linear flexibility in part-writing. Beforehand music likewise forbade consumption of the tritone, as its dissonance was connected with the devil, and composers regularly went to considerable lengths, via musica ficta, to prevent using it. In the newer triadic harmonic system, however, the tritone ended up being permissible, as the standardization of functional dissonance make its use in leading chords desirable.

Most harmony originates from two or much more notes sound simultaneously—but a work can imply harmony with only one melodic line by making use of arpeggios or hocket. Many pieces from the baroqueperiod for solo string instruments—such as Bach’s Sonatas and also partitas because that solo violin and cello—convey ethereal harmony v inference rather than complete chordal structures. This works produce a feeling of harmonies by utilizing arpeggiated chords and also implied basslines. The comprise basslines are created with low notes of quick duration that numerous listeners perceive together being the bass keep in mind of a chord. (See below):
