Which of the following represents the years of the Romantic Era in music?

The Romantic Era in music is generally recognized as spanning from 1820 to 1900. This period was characterized by an emphasis on emotion, individualism, and the expression of personal feelings, setting it apart from the preceding Classical Era. Composers such as Franz Schubert, Johannes Brahms, and Pyotr Ilyich Tchaikovsky emerged during this time, pushing the boundaries of musical forms and often integrating literature and visual arts into their compositions.

The other time periods mentioned do not align with the Romantic Era. The timeframe beginning in 1450 and ending in 1600 is associated with the Renaissance, known for its focus on polyphony and the birth of opera. The years of 1750 to 1820 mark the transition from the Classical period, during which composers like Haydn and Mozart were pivotal. Finally, the range from 1600 to 1750 corresponds to the Baroque period, noted for its elaborate musical styles and development of instrumental music. Thus, the correct answer clearly identifies the correct temporal context of the Romantic music movement.
