key term - Augmented Seconds

Definition

Augmented seconds are musical intervals that span three half steps, making them larger than a major second, which spans two half steps. This interval is unique because it introduces a dissonant quality that can add tension and color to music. The presence of augmented seconds can often be found in certain scales, particularly the harmonic minor scale, where they create distinctive melodic characteristics.

Review Questions

• How do augmented seconds differ from other musical intervals, particularly in terms of their construction and emotional impact?
  • Augmented seconds differ from other musical intervals primarily in their size and the number of half steps they encompass, spanning three half steps compared to the two half steps of a major second. This increased size contributes to their dissonant quality, often evoking feelings of tension or unresolved emotions within a piece. While intervals like major and minor seconds provide smoother transitions, augmented seconds introduce a more dramatic and distinct character, making them stand out in melodies.
• Discuss how the use of augmented seconds in the harmonic minor scale enhances its melodic structure.
  • The inclusion of augmented seconds in the harmonic minor scale enhances its melodic structure by adding unique tensions that distinguish it from the natural minor scale. Specifically, the augmented second occurs between the sixth and seventh degrees, which creates an upward pull towards resolution when moving to the tonic. This characteristic makes melodies written in the harmonic minor sound more expressive and dynamic, as composers utilize these intervals to convey drama and emotional depth.
• Evaluate the role of augmented seconds in various musical genres and their significance in contributing to overall musical expression.
  • Augmented seconds play a significant role across various musical genres by enhancing expressiveness and emotional depth. In classical music, they are often used to create tension that resolves into consonance, enriching harmonic progressions. In jazz, augmented seconds may appear in improvisations to add complexity and interest. Additionally, in popular music, their distinctive sound can evoke specific moods or themes. Overall, augmented seconds contribute meaningfully to musical expression by allowing composers and performers to explore contrasting emotions and create captivating musical narratives.
