The Bauyn Manuscript, a key collection of seventeenth century harpsichord and other music, displays the influence of various schools of composition on the writing and performance of the great clavecinistes of the mid-seventeenth century. The recording includes works of Chambonnieres and Louis Couperin, displaying their different styles which led Le Gallois to write that ''one touched the heart and the other touched the ear'', as well as other contemporary composers such as Hardel and d'Anglebert. The Denis harpsichord of 1658 is the extraordinary protagonist of this recording, in which Giulia Nuti explores the expressive capacities of one of the earliest extant French double-manual harpsichords, displaying how instrumental refinement enables performance choies. The approach is that of Giulia Nuti's award-winning first solo recording of eighteenth-century French harpsichord music, Les Sauvages, recorded on the Taskin of 1788, which received a Diapason d'Or.
