What is the Difference Between Cacophony and Dissonance?

🆚 Go to Comparative Table 🆚

Cacophony and dissonance are both terms used to describe harsh or unpleasant sounds, but they have distinct differences:

  • Cacophony refers to a combination of harsh and discordant noises, often creating a sense of chaos or discord. It is a broader term that can be applied to any harsh or unpleasant sound, not just in music.
  • Dissonance specifically refers to a lack of harmony or agreement between sounds or musical notes. In music, dissonance is often used intentionally by composers to create a sense of drama or suspense.

While both terms refer to loud and harsh sounds that are unpleasant to the ear, dissonance is usually intentional and depends more on the organization of sound for a jarring effect, rather than on the unpleasantness of individual words. In literature, cacophony and dissonance are used as literary devices to create a harsh or jarring effect. The main difference between the two is that cacophony refers specifically to the use of such sounds, while dissonance refers to the use of such sounds within a larger structure, such as a sentence, paragraph, or entire piece of writing.

Comparative Table: Cacophony vs Dissonance

Here is a table comparing the differences between cacophony and dissonance:

Feature Cacophony Dissonance
Definition Cacophony is the combination of harsh and discordant noises, often created by the repetition of consonants or the use of "explosive" or "stop" consonants like B, D, G, K, P, S, and T. Dissonance refers to a general lack of harmony among words and phrases, or a lack of harmony or agreement between sounds or musical notes.
Context Cacophony is more commonly associated with literature and can be used to create a sense of chaos, confusion, or loudness in text. Dissonance is more commonly associated with music and can refer to a lack of harmony or disharmony within a piece of music.
Purpose Cacophony is used deliberately to create a harsh, jarring effect or to add a musical effect to text. Dissonance is used deliberately to create a sense of disharmony or conflict within a piece of music or text.
Examples In literature, cacophony can be achieved through the repetition of consonants or the use of harsh, guttural, or dissonant sounds. An example of cacophony in literature is the use of the word "grinding" to describe the sound of something being ground or crushed. In music, dissonance occurs when two or more notes are played together, creating a sense of disharmony or tension. For example, a dissonant chord resolves into a nicer sounding chord to finish a song.

In summary, both cacophony and dissonance refer to harsh or discordant sounds, but they are used in different contexts and serve different purposes. Cacophony is more commonly associated with literature and is used to create a sense of chaos or loudness, while dissonance is more commonly associated with music and is used to create a sense of disharmony or conflict.
