What were some of the social and cultural influences on the music of the romantic period?

During this time in the Romantic Era, the umbrella term "classical music" began to be accessible for all people and not just the group of elitist social upper class. A more diverse group of people started to attend concerts. 

I addition to this, there were more woman composers. Woman not only started to write music but also started to perform and teach music as well. Some of these women include Fanny Mendelssohn and Anna Maria Mozart

In the Romantic Era, there was a deep sense of nationalism as well. There was pride in homeland and traditions embedded in music including folk songs and dances. 

It is true but it depends on camera, computer, programs, all that stuff

What do you mean by this?
