Final answer:
Composers of the Romantic era, such as Brahms and Tchaikovsky, borrowed from classical traditions and innovated within them, responding to the newly formed tastes of the middle-class audience. Their works continued to follow classical forms but conveyed the emotional intensity characteristic of Romanticism, and the music of the post-Romantic era evolved further with nationalistic themes and extended Romantic techniques.
Step-by-step explanation:
The question seems to ask about a composer who wrote music that both reflected the classical traditions and introduced elements of the Romantic era, aligning with the evolving tastes of a burgeoning middle-class audience. Romantic composers did not reject the constraints of the classical style but were inspired by classical maestros such as Haydn, Mozart, and especially Beethoven. Instead of rejecting the past, these composers innovated within the classical forms, adding emotional depth and complexity to their works. Composers like Brahms, Tchaikovsky, and Schumann composed works that honored the classical approach, adhering to established musical rules while also imparting the intensities of the Romantic movement.
The rise of the middle class significantly impacted the evolution of musical audiences during the Romantic period, shifting from the aristocratic patronage of the classical era to public concerts and festivals. This social change influenced composers who increasingly wrote for these larger, paying audiences and facilitated a burgeoning appreciation for music among a broader spectrum of society. Moreover, the post-Romantic era saw composers like Mahler and Strauss pushing Romantic elements to their limits, while others explored nationalism in music, imbuing their compositions with cultural specificity.
