This thesis explores the narrative and emotional potential of mundane objects within the framework of audiovisual installations. At its core is the concept of Verisimilar Art, a term developed by this research to describe works that blur the boundaries between reality and fiction, engaging audiences through immersive and plausible storytelling. By integrating fabricated narratives, soundscapes, and curatorial frameworks, it examines how installation art can use mundane objects to evoke memory, shape perception, and inspire curiosity. Four key questions guide this inquiry: How can everyday objects within art evoke emotional resonance and personal meaning? In what ways can sound objects and soundscapes contribute to the narrative depth of object-centric installations? What strategies underpin the creation of Verisimilar narratives? And how can curatorial and archival practices enhance the legitimacy of fictionalised works? This practice-based investigation includes a portfolio of five installations—Five Umbrellas, Flights of Fancy Pigeons, Deskscapes, Sounds | Familiar, and The Increasingly Convoluted Contrivances of Konrad Barsony—serving as a means to actively explore the central questions through process. Each of these works takes a unique approach to the exploration of mundane objects, memory, and perception, employing soundscapes as narrative tools and curatorial frameworks to enhance authenticity. Drawing on aspects of material culture, sound studies, and narrative theory, this thesis adopts a multi-disciplinary approach to develop innovative insights into the emotional resonance of objects and sound. It reflects on the iterative process of creating Verisimilar Art, highlighting the integration of theory and practice. By establishing Verisimilar Art as a framework for analysing and creating works that challenge traditional notions of authenticity, this research aims to further an understanding in contemporary art discourse. It underscores the potential of mundane objects and sound to enrich narrative-driven installations and highlights practice-led inquiry as an effective approach for advancing both theoretical and creative understanding
