Dissonanz

Moments of tension and resolution created by individual chords in a harmonic progression (a series of chords) are known as dissonance or discordant (tension) and consonance or concordant (resolution). Combining moments of tension and resolution within music helps to add interest and keep the listener engaged.

A baby crying, a person screaming and an alarm going off are all common examples of dissonance. These sounds are annoying, disruptive or put a listener on edge. Another useful reference is music, where dissonance is also a key concept.

Dissonance is perceived as an unpleasant or harsh sound produced by a collection of notes using dissonant chords.it often makes me feel angry and unsettled. the music has a tense and agitated mood feeling attached to it.

Chords that are dissonant contain notes who fit together in a way that our ear finds jarring or off-putting. Traditionally, consonant (pleasant-sounding) chords derive their notes from the harmonic series, a naturally-occurring relationship between a frequency and multiples of that frequency.

Some harmonies sound pleasing and stable, while others clash and seem unstable. The stable harmonies are called consonant, while the unstable harmonies are called dissonant. Consonant harmonies give a sense of serenity and rest to a piece, while dissonant harmonies create tension and anxiety.

The emancipation of the dissonance was a concept or goal put forth by composer Arnold Schoenberg and others, including his pupil Anton Webern.

dissonance in American English 1. an inharmonious sound or combination of sounds; discord. 2. any lack of harmony or agreement; incongruity.

lack of agreement : lack of agreement. the dissonance between the truth and what people want to believe. especially : inconsistency between the beliefs one holds or between one's actions and one's beliefs compare cognitive dissonance. b. : an instance of such inconsistency or disagreement.

Throughout the Baroque, Classical and Romantic periods a more subtle use of dissonance was in evidence with the use of pedal notes (or pedal points). By constantly referring to one note as the melody itself moves around we hear a fast-moving series of tension/release statements.

Aside from a purely physical level of definition, the perception of consonance and dissonance is entirely subjective - both on an individual level as well as cultural one. However, it is often taught under the ideas of good and bad, pleasing and irritating.

A seventh chord simply adds a diatonic third above the fifth of the triad - or, in other words, a seventh above the root. In the following example, a D-minor triad becomes a seventh chord with the addition of the pitch C: Example 18–1. Whereas a triad may be consonant, a seventh chord is inherently dissonant.

There are plenty dissonant pieces of music that have been recorded over the years. Some of the most dissonant pieces of music ever recorded include "The Rite of Spring" by Stravinsky, "The Music of Time" by Vangelis, and "I Can't Stop the Music" by ABBA.
