Tintinnabuli Generative Model v1.4 - Example

Tintinnabuli Generative Model v1.4 — Four-State Tintinnabuli Cycle Version 1.4 develops a generative model based on the tintinnabuli technique associated with Arvo Pärt, translating its characteristic relationship between a melodic M-voice and triad-derived T-voices into a systematic computational process. A modal M-voice is surrounded by upper and lower tintinnabuli voices whose pitches are determined relationally from an A-minor triadic field rather than through conventional harmonic progression. Across four successive regions, the model cycles through T+1/M/T−1, T+2/M/T−1, T+1/M/T−2, and T+2/M/T−2. The M-voice and rhythmic structure remain constant, while the changing T-voice positions progressively alter the registral and harmonic space surrounding the melody. In this way, Pärt's tintinnabuli principle becomes the starting point for a broader generative approach in which the M/T relationship itself functions as a formal parameter, allowing contrapuntal position and registral expansion to shape the larger musical form.
