Deciding Factors as to Consonance/Dissonance in Music

Consonance and dissonance are fundamental concepts in music that describe the quality of sound combinations. While the perception of consonance and dissonance can be influenced by various factors, understanding their deciding factors requires an examination of objective, subjective, and cultural elements. This article explores the key factors that contribute to the perception of consonance and dissonance in music.

Objective Factors

Harmonic Partials: One objective factor that influences the perception of consonance and dissonance is the presence of harmonic partials in the sounds considered. In the case of harmonic sounds with harmonic partials, the perception of consonance or dissonance is often based on the interaction and relationship between these partials.

Subjective and Cultural Factors

Convention and Style: The perception of consonance and dissonance is largely subjective, conventional, cultural, and style-dependent. The definition of what is considered consonant or dissonant can vary based on the musical style, historical period, and cultural context in which the music is created and appreciated.

Familiarity and Musical Expertise: Individual listeners may associate consonance with sweetness, pleasantness, and acceptability, while dissonance may be associated with harshness, unpleasantness, or unacceptability. However, these associations can also depend on the listener’s familiarity with the specific musical style and their level of musical expertise.

Alteration of Tones

Chromatic Alteration: Dissonance can arise from the alteration of tones from the diatonic scale. Any interval altered to a diminished or augmented interval is considered dissonant due to the chromatic alteration, regardless of whether the resulting interval is enharmonically equivalent to a consonant interval.

Context and Treatment

Musical Context: The treatment of intervals as consonant or dissonant can vary based on the musical context in which they occur. For example, an interval like a major second may be considered dissonant in a Baroque piece but consonant in a composition from the early 20th century or an atonal contemporary piece.

Style and Period: Different musical styles and historical periods may have different conventions regarding the treatment of intervals as consonant or dissonant. For example, jazz music often treats certain intervals differently than traditional Western music, leading to unique harmonic practices and perceptions of consonance and dissonance.

By considering these objective, subjective, and contextual factors, we can gain a deeper understanding of the complex nature of consonance and dissonance in music. The perception and interpretation of these concepts are not fixed but are influenced by a combination of objective acoustical properties, individual preferences, cultural norms, and artistic choices.

FAQs

What is the role of harmonic partials in determining consonance and dissonance?

Harmonic partials play a significant role in the perception of consonance and dissonance. When sounds have harmonic partials that align closely or create simple frequency ratios, they are often perceived as consonant. On the other hand, sounds with dissonant intervals between their harmonic partials are perceived as dissonant.

How does cultural context influence the perception of consonance and dissonance?

Cultural context has a strong influence on the perception of consonance and dissonance. Different musical cultures and traditions may have varying definitions of what is considered consonant or dissonant. Musical styles, historical periods, and cultural norms all shape our understanding and interpretation of these concepts.

What role does familiarity play in determining whether a sound is perceived as consonant or dissonant?

Familiarity with a specific musical style or genre can affect how we perceive consonance and dissonance. Listeners who are more familiar with a particular style of music may have different associations and expectations regarding what sounds are considered consonant or dissonant within that style.

How does chromatic alteration contribute to the perception of dissonance?

Chromatic alteration, such as altering tones from the diatonic scale, can lead to the perception of dissonance. Any interval that is diminished or augmented due to chromatic alteration is generally considered dissonant, regardless of whether the resulting interval is enharmonically equivalent to a consonant interval.

How does the musical context influence the perception of consonance and dissonance?

The musical context in which sounds occur can affect how we perceive their consonance or dissonance. The treatment of intervals as consonant or dissonant can vary based on the specific musical style, genre, and historical period. For example, an interval that is considered dissonant in one musical context may be considered consonant in another.

Are there differences in the perception of consonance and dissonance across different musical styles and periods?

Yes, there are differences in the perception of consonance and dissonance across different musical styles and periods. Each musical style and historical period may have its own conventions and expectations regarding what sounds are considered consonant or dissonant. For instance, the treatment of intervals in jazz music may differ from that in traditional Western classical music.

Can consonance and dissonance be objectively defined, or are they primarily subjective concepts?

While there are objective factors that contribute to the perception of consonance and dissonance, such as harmonic relationships, these concepts are primarily subjective. The perception of what is considered consonant or dissonant can vary among individuals and is influenced by cultural, contextual, and personal factors.

Do consonance and dissonance have universal meanings across all musical cultures?

No, the meanings of consonance and dissonance are not universally the same across all musical cultures. The perception and interpretation of these concepts can vary greatly depending on the cultural context. What may be considered consonant in one culture may be perceived as dissonant in another, highlighting the cultural relativity of these terms.
