In recent years Mr. Petric has turned equally to the work of research and writing. His first book The Concert Accordion - Contemporary Perspectives 2017 (330 p.) un-erases the sanctioned denunciations of accordion precursors by foreclosed eurocentric nihilism. Beginning with the strategic introduction of Giovanni Gagliardi's 1911 treatise Manualetto del Fisharmonicista to a broad international readership - a work ignored for 110 years - Mr. Petric's research delivers a recontextualization of accordion precursors that unfurls reciprocal resonances of the accordion across three centuries. "A towering achievement and a model of scholarship" (Goldman), the publication offers forensic illuminations of forgotten treatises, correspondance, musicology, theses, the names of more than 60 artists and pattern archeology of thirty-two instrument designs and patents from Milan, Bolzano, Camerano, Paris, Trossingen, Philadelphia, Manhattan and Chicago 1905-30.
In his Holistic Accordion- A Manifesto 2022 (50 p.) a book "...brilliantly written, theoretically astute and a joy to read" (Hutcheon), Mr. Petric explores the orthodox centre (McGilchrist) while advocating for the dignity of difference and greater transcendent perspective from the margin (Vonnegut).
His most recent book Accordion Dialogues and the Poetics of an Interpretive Art 2025 (165 p.) examines the ideal of artistic synthesis in a post-colonial concert art. The work is supported by an array of creative perspectives by thinkers, poets and artists including Enrico Cecchetti, Hanna Arendt, Nikolaus Harnoncourt and the visionary Hugo Noth.
Mr. Petric is also a reviewer and consultant of English translations and publications for the Paderewski Academy Press, Poland. His publications are available from www.augemus.de .
