Louis Couperin
The collection shows considerable Italian influence and many of the pieces are based on themes from miscellaneous composers of the era, including Girolamo Frescobaldi, Louis Couperin, Jean-Henri d'Anglebert, Johann Jakob Froberger, Francesco Cavalli and others. Some researchers (notably Jordi Savall) regard "Fugues et caprices" as an important precursor to Johann Sebastian Bach's "The Art of Fugue". Since the pieces of the collection are non-liturgical, they make Roberday one of the last composers of the French polyphonic tradition.
