I need a topic to discuss relevant to music appreciation.
One idea is to investigate the effects of music on our health. I believe there has been some research on this, in hospitals for example. Another topic might be the effect of music on developing brains. The research on this has, I think, been largely discounted, which is worth talking about, since there are many products being marketed to parents premised on this notion. Still another topic is the effect of music on sales. Supermarkets and many other kinds of stores have carefully selected music playing in the background.
On a more esoteric level, an essay on your own tastes in music or an essay on generational tastes in music might be interesting. You are likely to find that people's favorite kinds of music is the music of the teenage and early twenties years. Are our tastes formed then? Are your tastes being formed right now? What was forming tastes in the 1700's or 1800's? Who were the "Beatles" of those eras? Also on a generational note, each generation of parents has found the music of its youth quite appalling. Was this true in the Renaissance or in the Victorian era?
