Classical music is the art music produced in, or rooted in, the traditions of Western liturgical and secular music, encompassing a broad period from roughly the 11th century to present times. The central norms of this tradition became codified between 1550 and 1900, which is known as the common practice period. It should not be confused with the Classical Era.
European music is largely distinguished from many other non-European and popular musical forms by its system of staff notation, in use since about the 16th century. Western staff notation is used by composers to prescribe to the performer the pitch, speed, meter, individual rhythms and exact execution of a piece of music. This leaves less room for practices such as improvisation and ad libitum ornamentation, that are frequently heard in non-European art music and popular music.
The term "classical music" did not appear until the early 19th century, in an attempt to "canonize" the period from Johann Sebastian Bach to Beethoven as a golden age. The earliest reference to "classical music" recorded by the Oxford English Dictionary is from about 1836.
Antonio Lucio Vivaldi (4 March 1678 – 28 July 1741), nicknamed il Prete Rosso ("The Red Priest") because of his red hair, was an ItalianBaroque composer, priest, and virtuoso violinist, born in Venice. Recognized as one of the greatest Baroque composers, his influence during his lifetime was widespread over Europe. Vivaldi is known mainly for composing instrumental concertos, especially for the violin, as well as sacred choral works and over 40 operas. His best known work is a series of violin concertos known as The Four Seasons.
Many of his compositions were written for the female music ensemble of the Ospedale della Pietà, a home for abandoned children where Vivaldi worked from 1703 to 1715 and from 1723 to 1740. Vivaldi also had some success with stagings of his operas in Venice, Mantua and Vienna. After meeting the Emperor Charles VI, Vivaldi moved to Vienna hoping for preferment. The Emperor died soon after Vivaldi's arrival, and the composer died a pauper, without a steady source of income.
