The Baroque era, spanning from 1600 to 1750, was a time of dramatic change in music. Composers like Bach, Handel, and Vivaldi created complex, ornate works that pushed the boundaries of harmony and form. This period saw the rise of opera, oratorio, and new instrumental genres. Baroque music reflected the era's social and cultural shifts. The patronage system, religious conflicts, and growing middle class all influenced musical development. Key innovations included the basso continuo, concerto form, and emphasis on emotional expression through the doctrine of affections.
