Harmony

Definition

Harmony refers to the combination of different musical notes played or sung simultaneously to create a pleasing sound. It adds depth and richness to music, complementing the melody and enhancing the overall emotional impact of a piece. Understanding harmony is crucial as it interacts with other musical elements like texture, form, and the structure of compositions.

1. Harmony can be categorized into two main types: consonant harmony, which sounds stable and pleasant, and dissonant harmony, which creates tension and requires resolution.
2. In Western music, harmony is often built on scales and chords, with triads being the most common type of chord used to create harmonic progressions.
3. The use of harmony evolved over time, particularly during the transition from monophonic (single melody) music to polyphonic (multiple independent melodies) music.

Review Questions

• How does harmony enhance the emotional impact of a piece of music?
  • Harmony enhances the emotional impact by adding layers of sound that complement the melody. When different notes are played together, they create a richer texture that evokes various feelings. For example, consonant harmonies can convey feelings of happiness or peace, while dissonant harmonies can express tension or unease. This interaction between melody and harmony helps listeners connect more deeply with the music.
• Discuss the differences between consonance and dissonance in the context of harmony.
  • Consonance refers to combinations of notes that are harmonious and sound stable together, making listeners feel at ease. In contrast, dissonance consists of note combinations that create tension or a feeling of instability. This tension is often resolved by moving to consonant harmonies. Understanding these differences is essential for analyzing how composers create emotional dynamics within their music.
• Evaluate the role of harmony in the transition from monophonic to polyphonic music during historical periods.
  • The transition from monophonic to polyphonic music marked a significant evolution in harmony's role in composition. Initially, music consisted of single melodic lines without harmonic support. As composers began to explore multiple melodies occurring simultaneously, they developed more complex harmonic structures. This shift allowed for greater expressiveness and sophistication in musical compositions. Analyzing this transition highlights how harmony became integral to defining styles across various historical periods.
