From 1820 to 1910 was known as the Romantic period. Composers continued to use the forms that had been invented in the 18th century, but they also thought that personal feeling and emotion were very important. Music for orchestra sometimes told a story (programme music). Musicians who played their instruments brilliantly (such as Paganini) were worshipped like heroes. Beethoven and Schubert belong, in many ways, to this period as well as to the Classical period. It was a time when there were a lot of changes in society. After the wars that Napoleon had waged, there were not so many ruling aristocratic families. There was a lot of feeling of nationalism as countries united. 19th century music is often nationalistic: composers wrote music that was typical of their own country.
