Notation Through Time

Organum

For this fourth assignment, I do not have any media to post (if it was returned I can't find it). However were instructed to look at an organum composition and try to add chords that would harmonize with the preexisting melody. At first we attempted to use software like Sibelius, but that did not work out too well. So, I moved to a piano and a sheet of black staff paper. This assignment was difficult to me because it caused me to go back to what I learned in theory, so I could make sure that the chords I added would make sense. I ended up recycling the same chords over and over until the melody was over. 
Tonality was introduced in music during the baroque era. This can be explained as the use of major and minor keys as opposed to some group of random pitches, or modes.
