20th Century Composers vs. Romantic Period Composers

What's the Difference?

20th Century composers and Romantic period composers both pushed the boundaries of traditional music and experimented with new forms and styles. However, while Romantic composers like Beethoven and Chopin focused on expressing emotion and storytelling through their music, 20th Century composers such as Stravinsky and Schoenberg were more concerned with exploring dissonance, atonality, and unconventional structures. Additionally, 20th Century composers were influenced by the rapidly changing world around them, leading to a wider range of influences and a more diverse range of musical styles.

Further Detail


Both the 20th Century and Romantic Periods were significant eras in the history of classical music. The Romantic Period, which spanned from the early 19th century to the early 20th century, was characterized by emotional expression, individualism, and a focus on nature and the supernatural. Composers of this period, such as Beethoven, Chopin, and Tchaikovsky, wrote music that was often dramatic, lyrical, and deeply personal.

In contrast, the 20th Century was a time of great experimentation and innovation in music. Composers of this period, such as Stravinsky, Schoenberg, and Copland, broke away from traditional tonality and form, exploring new harmonic and rhythmic possibilities. The music of the 20th Century was often dissonant, fragmented, and challenging to listeners.

Harmony and Tonality

One of the key differences between 20th Century composers and Romantic Period composers is their approach to harmony and tonality. Romantic composers typically used traditional tonal harmony, with clear resolutions and functional chord progressions. Their music was often characterized by lush, rich harmonies that evoked strong emotions in listeners.

In contrast, 20th Century composers often abandoned tonality altogether, exploring new harmonic systems such as atonality and serialism. This resulted in music that was often dissonant and unpredictable, challenging listeners to rethink their understanding of harmony and tonality.

Rhythm and Form

Another difference between the two periods is their approach to rhythm and form. Romantic composers tended to use traditional forms such as sonata-allegro, rondo, and theme and variations. Their music was often structured and predictable, with clear divisions between sections.

20th Century composers, on the other hand, experimented with new forms and structures, often breaking away from traditional conventions. Composers like Stravinsky and Schoenberg used techniques such as polyrhythms, irregular meters, and aleatoric music to create music that was complex and unpredictable.

Orchestration and Instrumentation

Both Romantic Period and 20th Century composers were known for their innovative use of orchestration and instrumentation. Romantic composers, such as Wagner and Mahler, expanded the size of the orchestra and experimented with new combinations of instruments to create rich, colorful textures.

20th Century composers continued this tradition of experimentation, with composers like Messiaen and Ligeti pushing the boundaries of orchestration even further. They often used unconventional instruments, electronic sounds, and extended techniques to create new and unique timbres in their music.

Expression and Emotion

While both periods were known for their emotional expressiveness, the way in which composers conveyed emotion differed. Romantic composers often used melody and harmony to evoke specific emotions in listeners, with music that was deeply personal and introspective.

20th Century composers, on the other hand, often focused on exploring new ways of expressing emotion through sound. Composers like Cage and Stockhausen experimented with chance operations, electronic manipulation, and other avant-garde techniques to create music that was abstract and open to interpretation.

Legacy and Influence

Despite their differences, both 20th Century and Romantic Period composers have had a lasting impact on the world of classical music. The music of Romantic composers continues to be performed and celebrated around the world, with works like Beethoven's Symphony No. 9 and Tchaikovsky's Swan Lake remaining staples of the classical repertoire.

Similarly, the innovations of 20th Century composers have shaped the direction of contemporary classical music. Composers like Glass, Reich, and Adams have continued to push the boundaries of what is possible in music, inspiring new generations of composers to explore new sounds and ideas.


While the 20th Century and Romantic Periods were distinct eras in the history of classical music, they share a common thread of innovation and creativity. Both periods saw composers pushing the boundaries of what was possible in music, exploring new harmonic, rhythmic, and expressive possibilities.

By comparing the attributes of 20th Century and Romantic Period composers, we can gain a deeper understanding of the evolution of classical music and the diverse ways in which composers have sought to express themselves through sound.
