Structural Pitch Collections in Jaakko Mäntyjärvi's "Richte mich, Gott"

‘Richte mich, Gott' exemplifies Jaakko Mäntyjärvi's pluralistic compositional approach through an interlaced organization of tonal and non-tonal pitch content. The development of ideas in the text of Psalm 43 and the concluding doxology is depicted across both layers of pitch organization and governed by specific structural pitch collections: (0145) and (0257). Moreover, the organic transformation of these structural pitch collections' intervallic content emerges as a fundamental means of progression throughout the work, in turn influencing the intervallic content of surrounding tonal material. This process of transformation and its relationship to the text is revealed through tonal and pitch-class analysis; a flexible approach to segmentation; and an exploration of two-way and three-way symmetry, and the disruption thereof, in pitch space and pitch-class space. An understanding of the interrelationship between pitch material from the tonal and non-tonal layers of pitch organization can aid singers, conductors, and analysts in the efficacy of their study, preparation, and performance of the psalm. The accompanying appendix of targeted choral warm-ups in this document offers choirs a practical method for studying, internalizing, and performing the non-tonal pitch content in the work.
