The Romantic Period composers brought great changes to classical music. The Romantic period in the arts started in literature in the late 18th century as a reaction against the strict and formal approach of the Classical period. Romanticism brought a greater emphasis on the emotions and instincts of the artist as opposed to the intellect. Composers were looking for greater freedom of form and expression.

The era of Romanticism is generally divided into three shorter periods.

The Early Romantic Period, 1820 to 1850, was foreshadowed by Beethoven's later works. Composers of this period include Mendelssohn, Schumann, and Chopin.

The Middle Romantic Period, from 1850 to 1890, includes the works of Liszt, Wagner, Brahms, Tchaikovsky, Dvorak and Grieg.

The Late Romantic Period, from 1890 to 1910, includes the works of R.Strauss, Sibelius, and the late works of Grieg and Dvorak which are part of a "Nationalism" movement.

Felix Mendelssohn, 1809-1847. This German is considered a major Romantic Period composer. He was a child prodigy, and composed his first major work at age 17. At age 20 he conducted a performance of Bach's St. Matthew Passion, that sparked a renewed interest in J.S. Bach. Mendelssohn's works are characterized by restraint, refinement and sensitivity. He wrote symphonies, concertos, oratorios and piano pieces.

Robert Schumann, 1810-1856. This German is considered a leader of the Romantic Period composers. He wrote primarily piano music until 1840, when he began composing orchestral works and songs. His works had great emotional intensity, which foreshadowed his later nervous breakdown. He was an influence on Chopin and Brahms.

Frederic Chopin, 1810-1849. Born in Poland, Chopin settled in Paris. His piano music is known for its unprecedented heights of expressiveness. Chopin established the piano as a solo instrument, or as a dominating force in his piano concertos. He had an enduring relationship with female author George Sand. Chopin had a long illness that developed into tuberculosis. He wrote concertos, preludes, etudes, and sonatas.

Franz Liszt, 1811-1886. This Hungarian composer is regarded as the greatest pianist of his time. He was a "superstar" who thrilled audiences with his dramatic technique.

Johannes Brahms, 1833-1897. This German composer is considered one of the masters of the Romantic Period. His conservative style was at odds with some of the more dramatic composers of his day.
