Christoph Willibald Gluck was a composer who tried to make people take opera more seriously. In 1762 he wrote an opera called "" which was performed in Vienna. It had lots of choruses and ballet numbers, like French opera, but the words were in Italian and the music really concentrated on the story rather than being just a display for clever singers to show off. Some of its music is very famous today, e.g. the "Dance of the Blessed Spirits" which is played on a flute, and Orfeo’s aria "Che faró senza Euridice?" ("What shall I do without Euridice?").
