Harmonizing Plainchant on Keyboards: Exploring the Organum and Polyphonic Texture Approach

Organum and polyphonic texture are valuable techniques for harmonizing plainchant on keyboards. Drawing inspiration from the medieval period, these approaches add depth and richness to the original chant melody. In this article, we will delve into the process of harmonizing plainchant on keyboards using the principles of organum and polyphonic texture.

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 adding one or more voices to a chant melody, creating a rich and layered texture. By incorporating these techniques, the harmonization of plainchant can be transformed into a multi-dimensional musical experience.

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. By maintaining a strong link to the original melody, the harmonization retains the essence of the plainchant while adding new dimensions to the music.

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 judiciously selecting the intervals and maintaining a consistent harmonic structure, the harmonization can add depth and complexity to the original plainchant.

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, typically involving a progression of chords leading to a tonic or final chord. By incorporating this cadential progression, the harmonization brings the chant to a natural close, leaving the listener with a feeling of fulfillment.

In conclusion, harmonizing plainchant on keyboards using the organum and polyphonic texture approach opens up a world of musical possibilities. By starting in unison, building harmonic progressions, and employing a clausula vera, the original chant is transformed into a multi-voiced composition that retains its sacred character while embracing the richness of polyphony. Through these techniques, the keyboard player can create harmonizations that elevate the plainchant to new heights of musical expression.

FAQs

What is the organum approach to harmonizing plainchant on keyboards?

The organum approach involves adding one or more voices to a plainchant melody, creating a rich and layered texture. It draws inspiration from early polyphonic styles that emerged during the medieval period.

How do I establish a solid foundation when harmonizing plainchant on keyboards?

To establish a solid foundation, start by playing the harmonizing voices in unison with the chant melody. This ensures a close connection between the harmonizing voices and the original chant, maintaining coherence in the overall texture.

What is the role of parallel movement in harmonizing plainchant on keyboards?

Parallel movement involves gradually moving the harmonizing voice up by steps to a perfect fifth once the unison is established. This creates harmonic progressions that support and enhance the melodic line of the plainchant.

What is a clausula vera, and how does it contribute to the harmonization of plainchant?



A clausula vera is a cadence that provides a sense of resolution and finality to the harmonization. It typically involves a progression of chords leading to a tonic or final chord. Incorporating a clausula vera brings the harmonization to a satisfying conclusion.

Can I use the organum approach to harmonize plainchant on other keyboard instruments?

Yes, the organum approach can be applied to harmonize plainchant on various keyboard instruments, including the organ, piano, harpsichord, and synthesizer. The principles of establishing a foundation, parallel movement, and clausula vera can be adapted to suit the specific instrument.

Are there any guidelines or rules for harmonizing plainchant on keyboards?

While there are no strict rules, it is important to respect the character and essence of the plainchant when harmonizing on keyboards. Maintaining a strong connection to the original melody, creating coherent harmonies, and ensuring a satisfying conclusion are general guidelines to follow.

Can I experiment with different harmonization techniques while working with plainchant on keyboards?

Absolutely! While the organum approach provides a solid foundation, there is room for experimentation and creativity. Feel free to explore different chord progressions, voicings, and textures to add your unique musical interpretation to the plainchant.

Are there any specific resources or references I can use to further study harmonizing plainchant on keyboards?
