This document summarizes classical music history from 1730 to 1825 through four periods. It describes how the classical style emerged from the Baroque era, with composers like Haydn and Mozart establishing forms like the symphony and string quartet. Their works saw a shift to clearer textures, striking melodies, and integration of Baroque and classical elements. Younger composers like Beethoven then expanded on these styles, writing longer, more complex works that marked the late classical period and transition to romanticism.
