In "Intorno a un ritorno" (2025), Andrea Ravizza outlines a chamber music structure for voice and piano that serves as an analytical synthesis between formal rigor and the freedom of extemporaneous gesture. Dedicated to the jazz singer Carola Cora, the work explores the concept of Limen (threshold of perception), where the music does not proceed through linear progressions, but through a series of cyclical approximations to a recognizable generating core

The Lydian Horizon and Open Form

The composition is divided into eight autonomous fragments, equally distributed between the polarities of F Lydian and C Lydian. The Lydian mode is not intended here in a merely traditional-modal sense, but as a stable and suspended harmonic field—a chromatic horizon that allows sonic events to emerge and dissolve in a regime of "process transparency"[cite: 6]. The structure is conceived as an open form: the order of the fragments and the repetition of certain cells are entrusted to the sensitivity of the performers, transforming the execution into an act of exploring uncharted territories

Jazz as an Integrated Dialect

Consistent with Ravizza's poetics, jazz is not treated as a superimposed genre, but as an integrated "dialect" within the formal language[cite: 12]. The vocal part, characterized by extensive improvisational sections, utilizes the dark timbre and "intuitive music" of the soloist to transcend the fixity of the score[cite: 38]. The piano, of classical extraction, acts as an axis of orientation, creating a non-conflictual balance that recalls the concept of the "Double" and the dual relationship between heterogeneous identities.

Controlled Aleatoricism and Genesis of Material

Although the material originates from extemporaneous cells generated at the piano, the final writing is the result of a reworking that balances instinct and rule[cite: 5]. The use of controlled aleatoricism allows for the maintenance of harmonic and melodic coherence (the α core), ensuring that the form remains perceptible even in its most fragmented configurations[cite: 30]. The work thus constitutes an interactive sound ecosystem, inviting the listener to recognize what reappears under new resonances.
