Beethoven symphony originally intended to honor Napoleon

EROICA

This symphony was later dedicated to "the memory of a great man" after Beethoven famously scratched out Napoleon’s name in frustration over his imperial ambitions.

This clue refers to Beethoven's Symphony No. 3, which he originally titled Bonaparte in admiration of Napoleon’s revolutionary ideals. After Napoleon declared himself Emperor, Beethoven famously scratched out the dedication and renamed it Eroica (Italian for "heroic"). The answer is simply the symphony’s well-known nickname, capturing its bold, groundbreaking spirit.
