Based on Ritorni al nostro cor la bella pace from Salustia by Giovanni Battista Pergolesi (1710-1736), O Sing This Festive Day! is a majestic opening number for school programs or church services. Incorporating optional hand drum and trumpet (parts are included in the choral), it is also a good supplement for music history studies. O Sing This Festive Day! gives singers an excellent taste of Baroque music without being difficult to learn.
