Answer:
Romanticism
Step-by-step explanation:
The earliest evidence of romanticism in music comes with Beethoven. His symphonies, from the third, reveal a deeply personal and internalized music, as well as some of his piano sonatas, among which one can cite the Pathetic Sonata.
Other composers such as Chopin, Tchaikovsky, Felix Mendelssohn, Liszt, Grieg and Brahms have further advanced Beethoven's romantic ideal, leaving the formal rigor of classicism to write songs more in accordance with their emotions.
One fact is that, independent of the composer, romanticism in music has been characterized as a dramatic use of larger and smaller scale systems, creating a pleasant and harmonious sound.
