Many composers began writing music for bigger orchestras, with as many as 100 instruments. It was the period of "Nationalism" (the feeling of being proud of one's country) when many composers made music using folksong or melodies from their country. Lots of famous composers lived at this time such as Franz Schubert, Felix Mendelssohn, Frederic Chopin, Johannes Brahms, Pyotr Tchaikovsky and Richard Wagner.
