Richard Wagner [SEP] "Romantic operas" (1843–51)
Wagner's middle stage output began with "Der fliegende Holländer" ("The Flying Dutchman", 1843), followed by "Tannhäuser" (1845) and "Lohengrin" (1850). These three operas are sometimes referred to as Wagner's "romantic operas". They reinforced the reputation, among the public in Germany and beyond, that Wagner had begun to establish with "Rienzi". Although distancing himself from the style of these operas from 1849 onwards, he nevertheless reworked both "Der fliegende Holländer" and "Tannhäuser" on several occasions. These three operas are considered to represent a significant developmental stage in Wagner's musical and operatic maturity as regards thematic handling, portrayal of emotions and orchestration.
