The Leonardo Guitar Reserach Project aimed to increase the cooperation between Vocational Education and Training (VET) and the labour market within the field of guitar lutherie, by challenging luthiers and schools to join their forces in common development work. The project created an increased focus on environmental sustainability and use of non-tropical woods. Furthermore, this project aimed to develop the field of guitar making in a more sustainable direction, creating a European network on non-tropical woods in guitar building as well as a sustainable supply base of non-tropical woods for lutherie.The Leonardo Guitar Research (LGR) Project was a partnership project involving three renowned guitar lutherie schools (CVO Rivierenland, Belgium; Ikata, Finland; Lincoln College, England), one knowledge centre for lutherie (Cmb Belgium) and four highly regarded entrepreneurial luthiers (Rémi Petiteau, France; Chris Larkin, Ireland; Thomas Holt Andreasen, Spain; Lorenzo Frignani, Italy), together representing seven different EU-countries. The Leonardo Guitar Research Project aimed to make the educational curriculum for lutherie students more relevant to the future needs of luthiers/employers by introducing new teaching methods (where luthiers act as mentors for individual students, in combination with individual work placements) and integrating new study material into the curriculum (e.g. a handbook on the characteristics of non-tropical woods, a methodology for evaluating acoustic guitars and a teacher guide on environment and sustainability considerations). In order to produce this new study material, teachers, students and staff members of the partner organizations, together with the participating professional luthiers, did a lot of research on different aspects of guitar building with non-tropical woods. A part of this research was carried out by students and teachers of the three participating schools during three international workshops (in Finland, England and Belgium). In their own schools, students produced in total 44 project guitars, in order to define the differences (if any) between tropical and non-tropical woods in guitar building.The LGR project partners introduced lutherie students to use a wider range of woods in guitar making, specifically non-tropical woods. They did so in order to improve their skills and knowledge, increasing their chances on the labour market, and to provide them with a better appreciation of the environmental impacts of lutherie and the importance of sustainability in wood use. In addition to the VET benefits for the participating schools, the project itself is having a major impact on the future of guitar building in Europe. Many people believed that the very best high-end acoustic guitars can only be made with exotic tropical woods. But these woods are highly endangered. And they are becoming increasingly scarce as their supply becomes restricted through the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). When they are available a high percentage (est. >70%) has been illegally harvested. The LGR project has clearly shown that local sustainable non-tropical woods can be used to make guitars fully equal in sound acceptance to those made with traditional exotic tropical woods. This result has been accepted and promoted by the European Guitar Builders association to the extent that we are already seeing a mindset change and increasing use of local sustainable woods in guitar making across Europe. The activities and achievements of the Leonardo Guitar Research Project are fully consistent with EU2020 policy on education, climate change, innovation and employment.
