'...Arguably the most important historian in his field...' (Cardin PANM360) Mr Petric's publications explore a new ontology of authentic interpretation.
His first book The Concert Accordion - Contemporary Perspectives (2017,350p) respects memory with the first ever confirmation of the origins of the concert accordion, the recovery of Giovanni Gagliardi’s forgotten 1911 treatise Manualetto del Fisharmonicista, and 54 unknown instruments and builders 1890-1940. Cited as '...a towering achievement and a model of scholarship...' (Goldman), the book documents treatises, interpreters, correspondance, photographs and hermeneutic connections unprecedented in the literature.
Petric's Manifesto - A Holistic Accordion (2022,54p) cited as '..brilliantly written and theoretically astute' (Hutcheon) invites students to develop a personal artistic vision toward the implicit.
His Accordion Dialogues - and the Poetics of an Interpretive Art (2025,135p) is a collection of 22 essays in the form of conversations with masters Enrico Ceccheti, Nikolaus Harnoncourt, Hugo Noth and Colin Tilney that open pathways toward a new ontology.
His fourth book exploring accordion hermeneutics is pending. All titles are an organic expression of Mr. Petric's uninterrupted 40 year concert hall career.
