Progressive Cadence: A musical progression where the cadence moves from an unstable chord to a more stable one, often leading to a sense of continuation or anticipation rather than resolution.
Context and Significance
Progressive cadences play a crucial role in creating momentum within a musical piece. Unlike traditional cadences that resolve to a tonic, progressive cadences keep the music flowing, adding tension and energy. They are often used in genres that thrive on dynamic movement, such as jazz and contemporary classical music. By avoiding complete resolution, composers can maintain listener engagement and drive the piece forward, enhancing the overall narrative structure of the composition.
Historical Background
The concept of progressive cadence evolved alongside the development of more complex harmonic languages in Western music. During the late Romantic period, composers began exploring ways to extend musical phrases and delay resolution, which led to the frequent use of progressive cadences. This approach was further expanded in the 20th century with the advent of jazz and modern classical music, where harmonic exploration became a central focus.
Examples
In jazz, a common progressive cadence is the ii-V-I progression that delays resolution by moving through a series of dominant chords. In Debussy’s compositions, progressive cadences can be found where harmonic shifts emphasize movement rather than resolution. These techniques create a sense of forward momentum and are a hallmark of his impressionistic style.
