In recent years Mr. Petric has turned equally to the work of research and writing. In his first book The Concert Accordion - Contemporary Perspectives (2017. 330 p.) Mr. Petric recovers an authentic history ignored and forgotten since the 1860s. 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 - the publication illuminates responsible, reciprocal resonances of the accordion across three centuries in "a towering achievement and a model of scholarship" (Goldman) with the forensic delivery of forgotten treatises, correspondance, theses, the work and careers of more than 60 artists and an unprecedented 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 speaks to the role of intution and imagination in the contemporary concert hall.
His most recent book Accordion Dialogues and the Poetics of an Interpretive Art 2025 (165 p.) explores post-critical perspectives (Polyani) of artistic synthesis and a music with irony supported by companion artists and thinkers Enrico Cecchetti, Hanna Arendt, and Nikolaus Harnoncourt among others.
Mr. Petric is also a reviewer and consultant of English translations and publications for the Paderewski Academy Press, Poland. Future publications are planned. All are available from www.augemus.de .
