This book can be viewed in many ways as it explores the interdisciplinarity of research in violin engineering and art, being a valuable reference for readers interested in the acoustics of violins and in the science of materials used for making them. In this book, the wood science, the chemistry of varnish, the art and technology of violin making by luthiers and organologic context of violins, are put together giving a holistic view of the subject and complementing the large literature which exists on this instrument.  The book is addressed to teachers, researchers, makers of musical instruments and artists alike, this being a good premise for understanding the complexity of the interdisciplinary phenomena that musical instruments involve. This book is based on the material most of which was accumulated during the period 2019-2024, within the ACADIA (61PCE/2022) and MINOVIS (568PED/2020) projects, financial supported by The Executive Unit for the Financing of Higher Education, Research, Development and Innovation from Romania (UEFISCDI).
