A historian, writer and reviewer, Mr. Petric’s publications have enkindled an international risorgimento of the accordion’s history, un-erasing self-validating orthodoxies that have ignored, forgotten or trivialized the accordion’s dynamic artistic legacy in the concert hall since 1890. His first book The Concert Accordion — Contemporary Perspectives (2017), a “towering achievement, and model of scholarship” (Jonathan Goldman, AMS), introduced Giovanni Gagliardi’s forgotten 1911 Paris treatise Le Petit Manual de L’Accordéoniste, and the provenance of 14 ignored design patents from Catania, Milan, Bolzano, Paris, Manhattan and Chicago 1900-30. His second book The Holistic Accordion — A Manifesto (2022), a work “…brilliantly written… theoretically astute and a joy to read” (Linda Hutcheon, professor emerita, University of Toronto), introduced critical thinking and the role of intuition and imagination for the contemporary interpreter in concert hall. Mr. Petric’s third book, Accordion Dialogues and the Poetics of an Interpretive Art (2025) explores a wealth of perspectives by thinkers, poets and theorists as valued artistic companions to a “post-colonial” interpretive art in the contemporary concert hall.
