Out of Italian Gaetano Donizetti or Czech Bedřich Smetana, which opera composer lived and worked earlier?
Bedřich Smetana Bedřich Smetana (] ; 2 March 1824 – 12 May 1884) was a Czech composer who pioneered the development of a musical style which became closely identified with his country's aspirations to independent statehood. He is thus widely regarded in his homeland as the father of Czech music. Internationally he is best known for his opera "The Bartered Bride" and for the symphonic cycle "Má vlast" ("My Homeland"), which portrays the history, legends and landscape of the composer's native land.
Milanese Quartets (Mozart) The six string quartets, K. 155–160, were composed by Wolfgang Amadeus Mozart in late 1772 and early 1773. Because they were composed in Milan while he was working on his opera Lucio Silla, they are popularly known as the Milanese Quartets. Before this set was composed, Mozart had written one earlier string quartet (K. 80/73f in 1770), so these six quartets are ordinally numbered from No. 2 to No. 7. The quartets are written in a plan of keys of D-G-C-F-B♭ -E♭ following the circle of fifths.
