This project is the result of musical research carried out in various fields. It includes original works for harp and violin in a variety of compositional styles. The choice of different historical periods aims to focus on pieces that are rarely performed or, in the case of contemporary pieces, world premieres. The sonorities used, ranging from the 1800s to the present day, aim to highlight the technical, instrumental and musical potential of the Duo Vieuxtemps. The final objective of our work is to be able to take the listener on a musical journey, a sonic trip that offers a kaleidoscope of sensations, shapes and colours, with the intent of halting the perception of the passing of time and letting oneself be carried away by the sound.
