Harmonizing Plainchant on Keyboards: A Polyphonic Approach

Harmonizing plainchant on keyboards requires a careful understanding of the historical practices and techniques associated with this ancient musical tradition. In this article, we will explore an approach to harmonizing plainchant on keyboards that draws inspiration from the style of early polyphony known as organum. The goal is to create harmonies that complement the chant melody and enhance its expressive qualities.

Approach: Organum and Polyphonic Texture

Harmonizing plainchant on keyboards can be approached similarly to organum, a style of early polyphony that emerged during the medieval period. Organum involves the addition of one or more voices to a chant melody, creating a rich and layered texture. By applying the principles of organum, we can create compelling harmonizations that add depth and complexity to plainchant.

Unison Start: Establishing a Foundation

To begin the harmonization process, it is essential to establish a solid foundation by starting in unison with the chant melody. This unison start ensures that the harmonizing voices are closely connected to the original chant and that the overall texture remains coherent.

Parallel Movement: Building Harmonic Progressions

Once the unison is established, the harmonizing voice can gradually move up by steps to a perfect fifth. This parallel movement creates harmonic progressions that support and enhance the melodic line of the chant. By maintaining parallel perfect fifths, we can achieve a sense of consonance and stability in the harmonization.

Clausula Vera: A Satisfying Conclusion

To bring the harmonization to a satisfying conclusion, it is customary to employ a cadence known as a clausula vera. The clausula vera provides a sense of resolution and finality to the piece. It typically involves a progression of chords that leads to a tonic or final chord, creating a clear and conclusive ending.

In conclusion, harmonizing plainchant on keyboards can be approached through the lens of organum and early polyphony. By starting in unison, gradually introducing parallel movement, and concluding with a clausula vera, we can create harmonizations that enhance the beauty and expressive qualities of plainchant. By exploring these techniques and embracing the rich historical traditions, keyboardists can bring new life to this ancient musical form.
