During my senior year in high school I took a music theory class in which I learned the basics of music making. It occurred to me that music theory, just like language, has a comprehensive structure of which we can easily follow or break the rules. Recently I have become more musically active and have come to realize this structure as I realized the structure of language as I grew up and learned it. Just like and essay or a story, a musical piece has a beginning, middle, and an end. Notes can be stacked in various forms to form chords. There are different types of chords such a major or a minor chord. Minor chords tend to sound sad while majors sound happier. Then there's what is called a chord progression. The way in which you progress gives the songs it's own character reflecting the overall emotion and tonality of the overall piece. The other day I was hanging out with a friend who showed me this chart. This chart helps visualize the relationship of certain chords played in sequence with others. Yes it seems very complicated, but for those who are familiar with music terminology and notation this chart is a comprehensive map for chord progression on a major scale. It really helps when you try to fuse two musical ideas together or when you get stuck and can't find you way home (home being the One chord represented by a roman numeral). My music theory teacher always told me that a musical piece requires a sense of completion. Start on Ⅰ (one) end on Ⅰ. But just like a normal map, we are not limited to a specific path. Sometimes we create our own shortcut.
