There are many categories of turning points we can discover and value, but looking at the intervalic relationships in the harmony throughout these 1,650 years makes it much easier to determine the definitive turning points. This advantage comes from the notion that harmony can be studied in a very scientific manner. Composers undoubtedly use specific intervals for specific reasons in a period of history, which provides clear evidence of actual changes in music. For example, the medieval harmony from the middle ages contains mostly intervals of the perfect fifth, the perfect fourth, octave, and unison (typically on the final note). At the time, these intervals dominated the harmonic and melodic structures because of the musicians’ natural ability …show more content…

On the surface, this four-voiced organum seems very dissonant and rhythmically restless compared to the plainchant style with longer note-values and consonant harmonies. Pérotin obviously uses crunchy dissonances and a limping pulse to create this organum; however, if you look deeper into the harmonic contour of the piece, the perfect fourth, -fifths, and octaves still presents a hierarchy. All the climaxes of each phrase and cadences all end up on a strong octave or perfect fifth interval, and occasionally perfect fourths. This universal preference to make compositions revolve around the superparticular ratios opened up many possibilities to experiment with other intervalic hierarchies in later …show more content…

About a minute and a half into it, the harmony moves in full triads and thirds, particularly on the words “virginem ornare.” To achieve this, Dufay had a bass pedal tone with two voices on top in a combination of fourths and thirds (and sixths) above the bass. In doing this, he gains control of the direction of the harmony, simply because there are more options. Although the third was considered dissonant in the middle ages, gradually over time the interval was accepted as consonant on a cultural level. Eventually, composers began to realize that they could expand their creativity and control exponentially with the implementation of the third. Just as the original superparticular ratios in the medieval music opened the doors for thirds to be incorporated into the melodies and harmonies, these harmonic practices could have theoretically lead to any other
