These two projects are what my final project is going to be like at the end. The youtube video shows a program that can calculate and analyze emotions via camera, and the link provides a way to sort the music by mood. I learned from the second link that the mood of a song can be determined by the song’s length, BPM (beats per minute), and volume intensity. I think these two projects really helped point me in the right direction with how to proceed with my final project.
