The Classical period is before the Baroque period of music.
Jean-Jacques Rousseau, who was a musician and composer as well as a philosopher, wrote in 1768 in the Encyclopdie: "Baroque music is that in which the harmony is confused, and loaded with modulations and dissonances
"Common use of the term for the music of the period began only in 1919, by Curt Sachs, and it was not until 1940 that it was first used in English in an article published by Manfred Bukofzer
