Tonic

Definition

The tonic is the first note of a scale and serves as the home base or anchor point in tonal music. It establishes the key of a piece and provides a sense of resolution, making it fundamental in the development of tonality and functional harmony. The tonic not only defines the scale but also influences how other notes are perceived in relation to it, shaping the overall harmonic framework of compositions.

5 Must Know Facts For Your Next Test

1. The tonic is often referred to as the 'home' note because it is where melodies frequently resolve, providing a sense of stability.
2. In Western music, the tonic is typically associated with major and minor scales, influencing the mood and character of a piece.
3. The role of the tonic became increasingly prominent during the Baroque period, as composers began to explore functional harmony more rigorously.
4. Chords built on the tonic (the I chord) are central to establishing key relationships in tonal music, influencing how other chords function within a progression.
5. In Rameau's theories, the tonic is essential for understanding how harmony functions, as it serves as the reference point for all other harmonic movements.

Review Questions

• How does the tonic contribute to the overall structure of tonal music?
  • The tonic serves as the foundational note of a scale and is crucial for establishing the key of a composition. It acts as an anchor point around which other notes and chords revolve. By creating a sense of stability, the tonic allows composers to develop harmonic progressions that build tension and resolution, making it essential in defining musical form and structure in tonal music.
• Discuss how Rameau’s view on the tonic influenced his contributions to music theory.
  • Rameau emphasized the importance of the tonic in his theories of harmony and tonality. He viewed the tonic as not only a starting point but also as a reference for all harmonic relationships within a composition. His ideas on functional harmony underscored how chords relate to the tonic, particularly how dominant and subdominant chords create tension that resolves back to it. This framework significantly shaped modern understanding of tonal music.
• Evaluate the role of the tonic in both Baroque music and Rameau's harmonic theory, highlighting any contrasts or similarities.
  • In Baroque music, the tonic was pivotal for establishing clear tonal centers and guiding harmonic progressions through functional relationships. Composers utilized the tonic to create tension with dominant chords and resolve back effectively, crafting coherent musical narratives. Similarly, Rameau's harmonic theory positioned the tonic at the heart of his analysis, asserting its role in defining harmonic functions. While both recognized its importance, Rameau's theoretical approach offered more structured insights into how these relationships work within compositions, paving the way for further developments in music theory.

Related terms

Dominant: The dominant is the fifth note of a scale and plays a crucial role in establishing tension that resolves back to the tonic, creating a sense of movement in tonal music.

Subdominant: The subdominant is the fourth note of a scale and serves as a pre-dominant chord that often leads to the dominant, further enhancing the relationship between chords and the tonic.

Cadence: A cadence is a musical phrase that brings a sense of closure or resolution, often involving movement from the dominant chord back to the tonic chord.
