Pitch Shifting (Grgur Savić & Sanja Star)
Pitch Shifting occupies a position at the intersection of improvisational sound, generative media, and material–digital systems.
The practice focuses on the development of live audiovisual systems in which sound, image, and material processes interact in real time. These systems are not pre-programmed but unfold through feedback, gesture, and computational interaction.
Performances operate as emergent configurations in which acoustic instruments, live electronics, generative visuals, and material or sensor-based elements are integrated into a single dynamic system. These elements continuously influence one another through live interaction instead of functioning as separate components.
Research Framework
Pitch Shifting is research-driven. Each project investigates how perception is shaped within emergent audiovisual systems, and how audiences experience spatial, temporal, and material transformations within them.
Improvisation functions as a method for system activation, allowing each performance to develop as a unique and non-replicable configuration.
Expanded Practice
The practice extends into site-specific performances, interdisciplinary collaborations, and research residencies. Across these contexts, Pitch Shifting develops system-based approaches that adapt to different spatial, technological, and institutional conditions.
The focus remains on process-based work in which structure emerges through interaction rather than composition.
Performing Media
Pitch Shifting works with media as an active system, making visible the interactions between sound, gesture, computation, and material behaviour.

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.
