Hello. I am music artist Jin clobert. As a classical music major, a music college graduate, and a currently active music artist, I have often seen many people get frustrated in front of the high wall known as "Harmony." In particular, I felt that commercial harmony textbooks like those by Baek Byeong-dong or Applied Harmony are too vast and filled with theories that are difficult to apply to composition immediately. That is why I created this course. I have included only the core theories essential for actual popular music composition. I clearly explain why you are learning this and where and how it is used. You can vividly experience the theory by analyzing actual examples within K-POP music. We won't stop at simply memorizing theory; we will also cover the actual thoughts and decisions a composer makes while creating a song. I will help you naturally understand concepts that may have felt complex—such as intervals, Roman numerals, chords, inversions, secondary dominants, tensions, modal interchange, modulation, and money chords—within the context of music. Let's discover the hidden principles of harmony together by dissecting the chords of K-POP music. 🎵 A real composer's practical harmony lecture for real composition.
