This article presents a systematization of the harmonic fields specific to each natural mode of the diatonic collection, here defined as sets of diatonic triads functionally organized around a tonic. Based on the fundamentals of Functional Chromatic Modality, by Max Kühn and Pauxy Gentil-Nunes, the perspective adopted is that functionality is an intervallic and contextual phenomenon, not restricted to the Euroclassical tonal system. From the concept of the singular interval, the criterion for generating the triad fields — referred to as axes —pertaining to the tonic, dominant, and subdominant functions in the natural modes is established. It is concluded that the natural modes accommodate harmonically structured fields, where functions are defined by specific intervallic and syntactic relationships. Thus, the study broadens the scope of modality from a functional perspective, providing a theory applicable to both musical analysis and composition.
