Interior design of EYS Music School, providing a wide variety of musical instruments lessons. Music sessions with other students are considered by EYS as an important part of lessons, in addition to basic practices, in order to experience the joy of playing instruments. Therefore, our challenge was to express the pleasure of the sessions in the spatial design. Materials comprising the instruments (brass of a trumpet, stainless steel of a flute, spruce of an acoustic guitar, rosewood of a violin, and black paint of a piano) are used for wall tiles and furniture, in pursuit of a dynamic space as if the materials are having a session together. Furthermore, records of masterpieces are displayed on the wall shelves resembling five lines of a music staff, while creating a place to more closely feel the appeal of music.
