Drawing the line between these two styles is very difficult: some sections of Mozart's later works, taken alone, are indistinguishable in harmony and orchestration from music written 80 years later—and some composers continued to write in normative Classical styles into the early 20th century. Even before Beethoven's death, composers such as Louis Spohr were self-described Romantics, incorporating, for example, more extravagant chromaticism in their works (e.g., using chromatic harmonies in a piece's chord progression). Conversely, works such as Schubert's Symphony No. 5, written during the chronological dawn of the Romantic era, exhibit a deliberately anachronistic artistic paradigm, harking back to the compositional style of several decades before.
