No, Wolfgang Amadeus Mozart was not a Baroque composer. He was a prominent figure in the Classical period, which followed the Baroque era. The Baroque period, spanning roughly from 1600 to 1750, was characterized by composers like Johann Sebastian Bach and George Frideric Handel. Mozart, born in 1756, contributed significantly to the Classical period (approximately 1750-1820), known for its clarity, balance, and form.
Mozart’s compositions, such as his symphonies, operas, and chamber music, exemplify the Classical style. His work laid the groundwork for the Romantic period that followed. While Mozart was influenced by some Baroque elements, his music is distinctly Classical in nature.
