I want to know the answer to the following question:
The years 1804-1910 marked what era?
All the background I'm provided with is that "The 20th century calendar period (1901–2000) includes most of the early modern musical era (1890–1930), the entire high modern (mid 20th-century), and the first 25 years of the contemporary or postmodern musical era (1975–current).". Is that enough to answer the question?
