Antonio Vivaldi was born on March 4, 1678 in Venice. He composed baroque music.
His father taught him how to play the violin at a young age. In 1693 he began studying to become a priest and in 1703 he became one.
Later in 1703 he became the master of violin at the Pio Ospedale della Pieta orphanage. His students began to gain high esteem after leaving the academy. He remained, however a controversial teacher. Many times the board had to vote on whether or not they wanted to keep him on. In 1709 he lost his job. Two years later he was rehired and in 1716 he was promoted to the head of the music department. He began writing his masterpieces during this period.
It was around this time that he began writing operas, the most popular style of music around at that point. His first opera was Ottone in villa at the Grazeria theater in 1713. He continued to compose operas and was offered the poisiton of Maestro di Cappella by Prince Phillippp of Hessen-Darmstadt. This required him to move to Mantua where he continued to produce operas.
In 1722 he moved to Rome where he played for pope Benedict XIII. It was also during this time that he created perhaps his most well-known and best pieces, The Four Seasons. He was likely inspired by the Mantua landscape.
