Mr. Petric's writings revivify an emergent accordion epistemology with gestalt perspective. His first publication The Concert Accordion - Contemporary Perspectives (2017) introduced fresh perspectives of a rounded accordion art by introducing Giovanni Gagliardi’s forgotten 1911 treatise Manualetto del Fisharmonicista to an international readership and documentation of the origins of the concert accordion unprecedented in the literature. Acclaimed as '...a towering achievement and a model of scholarship...'(Goldman), Petric weaves a musicology of forgotten treatises, correspondance, photographs, and documentation of more than 60 interpretive artists, 54 unknown instruments and patents 1890-1950 .
His Holistic Accordion - a Manifesto (2022) builds on Gagliardi's trenchant 1911 treatise and Pierre Monichon's musicology (1972) . A theoretical work '..brilliantly written and theoretically astute' (Hutcheon), the title warrants approaches to embodied interpretation in the concert agora for students with curiosity and commitment.
His third book Accordion Dialogues (2025), a collection of 22 essays opens fresh pathways toward a transcendent art for young artists in conversations with artistic companions Enrico Ceccheti, Hanna Arendt, Nikolaus Harnoncourt, Bob Dylan, Hugo Noth and Colin Tilney among others.
Mr. Petric's writing is organic and complementary to his performances. His fourth book is pending.
