In the spring of 1747, J.S. Bach paid a visit to King Frederick the Great, where his son Carl Phillip Emmanuel was employed as a court musician. Curious to test Bach’s contrapuntal prowess, Frederick presented Bach with a subject to improvise two fugues, first one in three parts, and then one in six. Declining the second of these tests, Bach took Frederick’s subject home with him to create one of his most fascinating and iconic collections of music, The Musical Offering. This September, Filament joins forces with flautist Héloïse Degrugillier to present this musical feast for the mind and heart.
