Claude Balbastre is one of the French classical composers that don't get as much attention as Couperin, Clerambeault and Dandrieu. This really accessible Dialogue would be very suitable for a postlude or processional piece. I encourage you to explore the other works in this collection and his many Noels for the upcoming Christmas season.
