Joy instantly abounds as the well-edited keyboard introduction sets the tone for this impressive, yet approachable Baroque selection---the first movement of Vivaldi's masterwork of the same name. Choral phrasing is obvious, as we alternate between brief marcato statements and longer lines that deliver satisfying suspensions. As always, Dr. Liebergen includes an informative editor's note and a complete IPA pronunciation guide for the Latin text (eight words in total). This title is available in SmartMusic.
