Augmented triads

Definition

An augmented triad is a type of musical chord consisting of three notes: the root, major third, and augmented fifth. This unique chord creates a sense of tension and instability, often used to foreshadow transitions or resolutions in music. Augmented triads gained prominence during the late period of music as composers began to explore more complex harmonic structures, paving the way for the emotional depth found in Romanticism.

5 Must Know Facts For Your Next Test

1. Augmented triads can be built on any note, allowing for a wide range of harmonic possibilities in composition.
2. They create a unique sound due to the interval between the root and the augmented fifth, which is larger than a perfect fifth, contributing to their distinct tension.
3. Composers like Beethoven and Schubert utilized augmented triads to enhance emotional expression and drama in their works during the late period.
4. Augmented triads often serve as transitional chords, helping to bridge different harmonic areas within a piece.
5. In orchestration, augmented triads can be effectively used to create vivid colors and textures in musical passages, enhancing the overall atmosphere.

Review Questions

• How do augmented triads function within harmonic progressions during the late period of music?
  • Augmented triads function as transitional chords within harmonic progressions, creating a sense of tension that often resolves into more stable chords. They can serve as pivot points that lead from one key area to another, facilitating smooth modulations. Their unique sound provides composers with tools to convey emotion and suspense, which became increasingly important in late period compositions leading into Romanticism.
• Discuss how composers like Beethoven and Schubert used augmented triads to enhance emotional expression in their works.
  • Composers such as Beethoven and Schubert embraced augmented triads to evoke strong emotional responses in their music. By incorporating these chords into their harmonic vocabulary, they could amplify feelings of tension or longing. Their strategic use of augmented triads often highlighted moments of dramatic change or significant emotional shifts within their compositions, making them integral to the expressive landscape of late period music.
• Evaluate the impact of augmented triads on the development of harmonic language leading into Romanticism.
  • The impact of augmented triads on harmonic language was profound, as they helped lay the groundwork for the richer and more complex harmonies found in Romantic music. By introducing greater instability and tension through augmented chords, composers expanded their expressive capabilities and created more dramatic narratives in their works. This shift towards chromaticism and innovative chord structures ultimately influenced subsequent generations of composers, setting the stage for the evolution of modern harmony.
