"""Music doesn't need language"" is an international cooperation project whose main objective was to influence the level of acceptance of cultural diversity among young people between 9 and 17 years old in a school in Laskarzewo, Vidin, Zagreb, Rokiskis and Kardla. Music and dance was the main area in which we planned activities to achieve the main objectives of our project. We wanted to encourage and involve students in social dialogue. In the course of our project we tried to focus on the development of intercultural competences in young people, and we planned subsequent activities in such a way that they would transfer these values to their closest environments, increasing the level of tolerance, sense of unity and European community among their family members, friends, closer and further acquaintances. The aim of the project was also to prepare students to consciously plan their educational path, make professional choices and get to know other cultures. Through the implementation of the project we enriched the educational offer of schools and thus made it possible for all our students to develop better. We have included students with special educational needs in the project, which has significantly increased the level of tolerance among the recipients of our undertaking. In the face of the COVID-19 pandemic, we decided to increase the involvement of ICT tools in the project activities. In this way, we managed to motivate students between 9 and 17 years of age in schools in Łaskarzew, Vidin, Zagreb, Rokiskis and Kardla to acquire and improve their skills in using modern ICT tools, learning foreign languages and searching for innovative learning methods. The project also aimed to improve the professional competences of the teaching staff. Participation in the training entitled ""The influence of music on the psycho-physical development of children and young people"" raised the level of teachers' knowledge of the use of music and dance in the course of their pedagogical work. During the project activities, teachers participating in classes conducted by partner schools exchanged experiences, compared methods of implementing particular classes, and transferred the best solutions to their own schools. In order to share the acquired knowledge and the developed solutions, we have created a series of lesson scenarios using these good practices. The scenarios contain all the necessary attachments, so that they can be used by any teacher, form tutor or other interested person. We would like to make them available to a wider audience, therefore, we created a project catalogue, in which the developed scenarios can be found. The aim of the project was also to promote the school on a local, regional and even international level, to strengthen cooperation between the school and parents, as well as other representatives of the local environment. We were able to do this during the mobility, but also on the occasion of other project events. We encouraged parents, friends, local entrepreneurs and local authorities to take an active part in preparing for international meetings. Also the local media were interested in our activities, they placed information about further project events. The main coordinator of the project, a school from Łaskarzew, was invited to participate in a conference on developing intercultural competences, where J. Głaszczka presented information about the project we were implementing. Our project has been noticed as an example of activity aimed at shaping a sense of unity and respect at the level of European community among young people. Within the project activities the participants prepared presentations, films, conducted workshops, competitions, national evenings, meetings and concerts as well as common games. Among the developed results there are material products, i.e. the project catalogue, scenarios of classes with the use of music and other forms and methods of didactic work, information materials, photographs, the website, ""The project wall"", presentations, project materials, music and dance groups of students, developed ways and space for communication between the project partners.The effects and results of the realised project activities will have a long-term impact on the participants and other environments more or less related to our schools. Information about the project, photos and videos can be found on YouTube, the project website, in local and regional media, in social media, as well as in information and promotional materials of partner schools and the towns where we live. The results and tools created as part of the project will be available to a wide range of stakeholders, will be placed in the libraries of partner schools, and their ease of modification will allow all stakeholders to adapt them to individual needs and use them for a wide range of purposes."
