This lecture introduces the brilliant and exuberant Baroque era. We differentiate between the measured elegance of Renaissance music and the extravagant emotionalism of Baroque music. Special attention is paid to the scientific and investigative spirit of the Baroque and its impact on the arts of the era. The Baroque artistic duality of emotional extravagance and intellectual control is examined as a manifestation of the scientific and philosophical currents of the time. The lecture concludes with a musical example the genre of French overture.
