Composed in 2025 and dedicated to Umberto Beccaria and Maria Alejandra Jimenez (Anamorfosi Duo), ohne Worte for violin and piano represents an advanced synthesis of Andrea Ravizza’s research into the relationship between algorithmic determinism and the phenomenology of gesture. The piece was premiered as part of the Lied project, a tour spanning major concert halls across Italy and Switzerland.
Algorithmic Structures and Sound Bands
The genesis of the harmonic material is rooted in complex algorithmic systems designed to occupy predefined harmonic fields, creating a sound fabric of extreme density. The composition unfolds through the evolution of sound bands (Streifen) that expand and contract within the pitch space. This material manipulation of sound allows the score to move between stasis and transformation, where the harmonic coherence of the generating nucleus remains perceptible despite continuous mutations in volume and spectral density.
Orchestral Interaction and Three-Dimensionality
From a technical standpoint, Ravizza treats the duo as a quasi-orchestral entity, divided into three independent yet interconnected voices: the piano’s left hand, its right hand, and the violin. These three entities interact in a tight dialectic, acting as vectors that dilate or compress the sound bands. The piano, in particular, is explored through its physical structure (with performance notes indicating play on the internal iron crossbeams IB, IIB, IIIB), transforming into a meta-instrument capable of unusual resonances.
Temporality and Spectral Influence
The rhythmic aspect of ohne Worte is characterized by processes of density and rarefaction that recall the poetics of Gérard Grisey. These temporal oscillations are not mere tempo changes, but true expansions and compressions of the "flesh" of time. In moments of heightened restlessness, the character shifts into Violento, a phase where the value of the individual note is subordinated to the power of the gesture. In these liminal zones, performative impetus prevails over micrometric precision, emphasizing the visceral and intuitive component of the performance.
Formal Symmetry and Dissolution
The formal structure follows a mirror-like arc. The opening and closing are marked by crystalline piano tolls describing a shifting sound band. While the beginning moves from temporal rarefaction toward progressive compression, the finale operates in reverse: a compressed mass that gradually dissolves into silence. The violin accompanies this dissolution with an ascending glissato into the highest register—an explicit homage to the string writing of Salvatore Sciarrino—until reaching the last audible threshold, where the sound resolves into the absence of words.
