”Music without frontiers” is a project intended for vocational secondary music schools. It involves a 3-week vocational training course taken by students in several of the following educational institutions: Helsinki, Lahti, Joensuu, Madrid, Funchal, Glasgow, Prague and Warsaw. The students taking part in the project have reached an advanced level of instrument playing, which enables them to gain professional experience in chamber ensembles and orchestras. In addition, the students will master their skills in individual instrument lessons and get to know the culture of the host country. Each mobility will reach its culmination in the concert with European peers. ZPSM no 4 in Warsaw is planning to send 5 groups of students with their guardians (30 mobilities altogether) to 5 selected European schools. ”Music without frontiers” is a project which aims to improve the quality of vocational music education. It allows raising the performance level of school concerts, which are an important element of artistic development and practical preparation for a future career as a professional musician. School concerts serve as useful training of practical skills involved in group music play. The work of a professional musician often requires cooperation with musicians of many nationalities under the supervision of conductors from various countries. It also involves constant travelling and adjusting to various conditions. Therefore, the training in a partner educational institution is the best preparation for future career as a professional musician. Participation in a training course abroad will support the beneficiaries in their intention of continuing their education and may facilitate finding a job in the future. The main purpose of the project is improving the teaching methods used in vocational education for students of secondary music schools. The project also serves to introduce the European dimension to vocational music education.
