Pitch Shifting (Grgur Savić & Sanja Star)
Pitch Shifting develops systems in which sound, image, and material processes are continuously translated into one another. Nothing remains in place; elements shift function, reappear elsewhere, and return altered.
The work does not aim for correspondence, but for misalignment—where a signal does not fully arrive, where a gesture exceeds its form, where translation produces difference instead of equivalence.
What emerges are configurations that hold together without stabilising, shaped by modulation, drift, and partial synchronisation.
Research Framework
Translation is not treated as transfer, but as transformation. Each system is constructed so that movement between media introduces delay, distortion, and deviation.
Modulation operates as a gradual re-writing of relations: changes accumulate without resolution, producing structures that remain open and contingent.
Improvisation enters as a way of navigating this instability—less a tool for expression than a means of staying inside processes that cannot be fixed in advance.
Expanded Practice
The work extends across performances, installations, and collaborative situations, each acting as a reconfiguration of the system.
Context does not frame the work—it interferes with it. Spatial conditions, technical setups, and institutional constraints become active variables that redirect how translations occur.
Performing Media
Media are not aligned but set into tension. Sound, image, computation, and material behaviour operate through mutual displacement, continuously shifting roles and functions.
The work exposes these movements without resolving them, allowing forms to emerge through translation and to remain unstable in their appearance.

Pitch Shifting develops situational performance systems in which sound, image, and material processes interact through feedback, gesture, and real-time modulation.
OUTBOX — Experiments in Performance
OUTBOX is a live audiovisual configuration within the Pitch Shifting system developed by Grgur Savić and Sanja Star.
The work explores interactions between sound, live electronics, and real-time manipulated 3D visual systems. Visual material is constructed through generative processes and then actively manipulated during performance, responding to sonic input and system behaviour.
Acoustic instruments, amplified objects, electronics, and visual systems operate as interconnected components within a single evolving environment. Each element influences the others through feedback and real-time modulation.
OUTBOX constructs temporary audiovisual environments in which sound and image continuously shape spatial and temporal perception.

SEAS OF MINTAKA — Navigating the Cosmic Soundscape
Seas of Mintaka is a situational audiovisual configuration within the Pitch Shifting system.
The work explores how sound and image can function as navigational structures within an evolving perceptual environment.
Grgur Savić develops layered sonic material combining acoustic, electronic, and textural processes. Sanja Star works with real-time manipulated 3D animation and audio-responsive visual structures that evolve during performance.
The system integrates sound and image as interdependent processes that shape spatial and temporal perception. Visual material is not pre-rendered as a fixed layer, but continuously transformed in performance in relation to sonic dynamics and system behaviour.

INFILTRATION: A SONIC AND VISUAL EXPLORATION OF THE UNKNOWN
INFILTRATION is a live configuration within the Pitch Shifting system focused on perception under conditions of reduced visibility and transformation.
The work operates through tightly coupled sound and image processes in which extended instrumental techniques and real-time manipulated visual systems interact continuously.
Grgur Savić transforms acoustic sources through electronic processing into unstable sonic structures. He uses Max/MSP as a system for triggering and shaping sound textures in real time. Sanja Star develops visual environments based on generative 3D material that is actively shaped during performance and responds to sonic intensity, density, and spatial change.
The system is designed as a shifting perceptual field in which sound and image operate as active components of transformation.

UN:MATERIAL: MICRO-SONIC ACTIONS, TACTILE MANIPULATIONS, AND SUBTLE MATERIAL INTERACTIONS. SOUND EMERGES FROM PROXIMITY, TEXTURE, AND PRESSURE, FOREGROUNDING LISTENING AS AN INTIMATE, BODILY, AND MATERIAL PRACTICE.
un:material is a hybrid audiovisual research-performance exploring the performative dissection of material objects and how materials, computers, and physical actions work together. The work operates as a format in which objects are examined, deconstructed, and operated on through close, precise, and often microscopic actions, transforming them into a site of sonic surgery.
Using artefacts alongside his main instruments (alto and soprano saxophone), Savić performs a surgical examination of the instrument, using extended techniques that are amplified and electronically processed to transform material forms into forensic sound procedures.
Combining audio-reactive 3D animation, live visual improvisation, and amplified material actions—drawing gestures on wearable elements and amplified clothing—Sanja treats the media format as structural and performative material, also generating sound from objects as part of the performance system.
Through continuous negotiation of acoustic, electronic, visual, and physical processes in real time, the work operates as a clinical probe into audiovisual systems, revealing their conditions and inviting attention to mediation, perception, and the shifting boundary between material and immaterial.
un:material is situated within contemporary practices of experimental music, generative media, and artistic research, and is conceived for performance, installation, and research-oriented contexts.
