The romantic period of music was known for

Vibrant and unexpected key changes
Little use of dynamic changes
Few notable composers
Minimal sense of storytelling

I'm sorry, but that's not correct. The Romantic period of music, which took place from the late 18th century to the early 20th century, was actually known for several other characteristics:

1. Expressive and emotional melodies: Composers focused on conveying a wide range of emotions through their music, often using long, singing melodies to evoke intense feelings.

2. Expansion of the orchestra: Composers began to explore the full potential of the orchestra, expanding it with new instruments and increased complexity. Orchestras grew larger and more diverse, allowing for more lush and dramatic soundscapes.

3. Dynamic changes: Composers made frequent use of dynamic changes, ranging from delicate and soft passages to powerful and thunderous sections. This helped to create dramatic contrasts and heighten emotional impact.

4. Rich harmonies: Composers in the Romantic era often used rich, complex harmonies to convey the depth and complexity of human emotions. They experimented with chromaticism and dissonance, pushing the boundaries of traditional tonality.

5. Program music and storytelling: Many composers in the Romantic period were inspired by stories, poems, and other non-musical sources. They created programmatic works, such as symphonic poems and character pieces, that aimed to tell a specific story or depict a particular scene or emotion.

6. Virtuosic performances: The Romantic period saw the rise of virtuoso performers, particularly in the field of piano music. Composers wrote technically demanding pieces that showcased the skills of these performers.

7. Increased individuality: Composers in the Romantic era began to value individual expression and creativity. They sought to establish their own unique musical voices, often challenging traditional forms and structures.

Notable composers from the Romantic period include Ludwig van Beethoven, Franz Schubert, Frédéric Chopin, Franz Liszt, Johannes Brahms, Richard Wagner, Pyotr Ilyich Tchaikovsky, and Gustav Mahler, among many others.
