Nicola Porpora was a late seventeenth-century Italian opera composer who was best known as a sought-after vocal teacher who taught individuals such as Joseph Haydn, Metastasio, and Farinella, the Italian castrato singer whose vocal powers were renowned in Italy, England, and other European countries. Porpora composed cantatas with well-developed recitatives as well as sonatas for the violin and basso continuo along with lieds and art songs. Porpora's vocal style was important to those who sought to perform in operas, since all characters and plots are demonstrated through song rather than speech. For the vocalists in operas, music is the drama and Porpora had the ability to convey to the students the fine art of vocal performance.
As Nicola Porpora incorporated the ideals of vocal effects through the correct production of sound to vocal compositions such as arias, lied, art songs, and recitatives to create the proper combination of content and form, the Unificationist ideal of unity of content and form appears to mirror Porpora's philosophy. Unification thought seeks the ideal of the unity of content and form to create the harmony and order needed to establish a peaceful relationship between entities. The need for cooperation between all of humanity and a loving God is a tenet of Unificationism as God and mankind act as co-creators of an ideal world.
Nicola Porpora exemplified the cooperation between humanity and God with his teaching of the gift of man's musical voices to be used towards the preparation for life in the spiritual realm.
