The Sonata a due, since the end of the 17th century, has been a highly fertile ground for experimentation, giving rise to a new conception of musical style: the two-part writing. Fabiano Martignago and Angelica Selmo extract from their “musical chest” a well-thought-out journey within a genre that reached its peak of popularity in the 18th century. Moving between original pieces and transcriptions, the two young performers, already renowned soloists, rely on the famous names of Telemann and Vivaldi. However, they also present the rare music of two composer-performers, both of whom, originating from Italy and Germany, found their way into English musical life: Francesco Barsanti and Johann Ernst Galliard.
