The study of music theory is often divided into two distinct camps: the descriptive, which seeks to analyze existing repertoire, and the prescriptive, which seeks to provide rules for new composition. In Teoria Musicale, Luigi Rossi navigates a path between these two poles. While grounded in the traditions of the Partimento and the conservatory culture of Italy, Rossi’s methodology anticipates the structuralist approaches that would later dominate Anglo-American music theory.
This paper aims to deconstruct the layers of Rossi’s treatise. We will begin by situating the work within its historical and pedagogical context. Subsequently, we will explore his treatment of the harmonic series and fundamental bass, his rigorous methodology for voice leading, and his approach to formal analysis. By dissecting these components, we can better appreciate the enduring relevance of Rossi’s theoretical architecture. Luigi Rossi Teoria Musicale.pdf
Obiettivo: Comprendere come la linea melodica interagisca con il basso in una cadenza autentica in minore.

Domanda: Perché nella voce superiore si evita il Si naturale (sensibile) sulla triade di Sol, pur essendo la dominante?
Risposta: Il Fa presente al secondo movimento funge da nota di passaggio discendente. L’introduzione del Si naturale creerebbe un tritono eccedente con il Fa (intervallo di quarta aumentata), distruggendo la linearità del moto opposto. Si applica quindi la regola di Rossi: "Nel contrappunto stretto a due voci in tonalità minore, la sensibile si impiega solo se la settima di dominante è esplicitata o se la linea melodica procede per grado congiunto ascendente." Domanda: Perché nella voce superiore si evita il
A central pillar of Rossi’s Teoria Musicale is the justification of harmony through acoustics. Like Jean-Philippe Rameau before him, Rossi anchors his theory in the harmonic series (the serie degli armonici). He posits that the major triad is not merely a cultural convention but a natural phenomenon derived from the physics of sound.
Rossi utilizes the concept of the Basso Fondamentale (Fundamental Bass) to explain chord roots and inversions. However, Rossi distinguishes himself through his rigorous classification of dissonance. He categorizes dissonances not just as "non-chord tones" (note di passaggio), but as integral components of the harmonic fabric when resolved correctly.
The treatise details a hierarchy of consonance and dissonance that guides the student from simple triadic construction to complex seventh and ninth chords. Rossi argues that the tension between the natural acoustical hierarchy (the dominance of the fifth) and the artificial construction of the scale creates the dynamic energy of tonal music. This dialectic between nature and artifice is a recurring theme throughout the text.
