1. Classical Period Vocal Music

3. Opera Reformation of the opera seria, or serious opera,dramatic with historical plot. During the same time, the opera buffa, or comedic opera, began developing. This type of opera was in sharp contrast to the opera seria. It catered more to the people who wanted to "revolt" against the more serious and dramatic opera.

4. Church music now resembled operatic music more than ever before. Almost all composers of church music during the Classical era also composed operatic music. Masses Oratorio became operatic styled pieces of literature for the orchestra, the solo voice, and the chorus. Duets and arias even resembled operas; the only feature that distinguished them from opera was their texts.

Credo- Credo means Creed of Belief. 4. Sanctus - Sanctus means Holy. 5. Benedictus- Benedictus means Blessed. 6. Agnus Dei - Lamb of Godmeans Lamb of God.
