Bach – Toccata and Fugue in D minorOne of the most famous chants is Dies Irae. It was composed in the 13th century. It is a typical example of a Gregorian Chant. It is religious, as was almost all music of the time. It features monks chanting religious text.Vivaldi?s ?Four Seasons? is by far his most famous work.

The Hallelujah chorus is what most people remember or know from the entire piece. It is a religious piece that is composed in typical Baroque fashion.There isn?t a child who loves Halloween that is not familiar with this melody. It is dark, almost sinister.
