I find an educated video online about the relationship between music and math. Beethoven was able to convey emotion and creativity using the certainty of mathematics. The simple pattern of triplets actually follows a sophisticated mathematical rule. It is surprising that there is rational mathematical reason for why we are moved by the Moonlight Sonata by Beethoven. To relate to what we learned in class, this evidence also proves music is universal since all music are constituted by existed keys on the scale and combinations of different chords. By combining different chords together and putting them into different tempo, we have different styles of music. However, all music is made of the same elements and follows the similar rules.
