Intended to ‘instruct us and elevate our souls’, the œuvre for keyboard of Bach allows us to travel to concertante Italy and invites us to dance on improvisation. From the moving Capriccio on the Departure of a Beloved Brother to the Italian Concerto by way of Partita no.1, the pianist Claire-Marie Le Guay offers a portrait of Bach that reveals the multiple facets of his genius: the virtuoso improviser, the pedagogue, the builder of cathedrals in sound.
