Why secular music became more important than sacred music?

Secular music gained prominence over sacred music due to several cultural and societal shifts, particularly during the Renaissance and Enlightenment periods. The rise of Humanism emphasized individual expression and the human experience, leading to a greater appreciation for secular themes and forms. Additionally, the expansion of the middle class and the development of new musical forms, such as Opera and popular song, made secular music more accessible and relatable to a broader audience. This shift reflected changing values within society, where entertainment and personal expression began to take precedence over religious themes.
