Giovanni Battista Pergolesi

Giovanni Battista Draghi usually referred to as Giovanni Battista Pergolesi (Italian: [perɡoˈleːzi, -eːsi]), was an Italian Baroque composer, violinist, and organist, leading exponent of the Baroque; he is considered one of the greatest Italian musicians of the first half of the 18th century and one of the most important representatives of the Neapolitan school.

Despite his short life and few years of activity (he died of tuberculosis at the age of 26), he managed to create works of high artistic value and historical importance, such as La serva padrona (The Maid Turned Mistress), which played an important role in the development and diffusion of the opera buffa in Europe, L'Olimpiade, considered "one of the finest opere serie of the early eighteenth century", and Stabat Mater, which is among the most important works of sacred music of all time.
