Vivaldi, one of the greatest baroque composers, has a very interesting story. He ran an orphanage in the 18th century in Italy that became famous all over the western world for its musically talented children. A lot of his pieces were written for specific children in his school. Vivaldi learned the violin from his father, and was trained as a priest. He was nicknamed “the red priest” for his red hair and was apparently somewhat sure of himself, having claimed once he can compose a concerto faster than it can be copied.
Vivaldi wrote over 500 pieces, most of which are lost today. He is considered one of the greatest musical landmarks in history, having inspired many composers that followed him, including J.S.Bach and others.
