No dusty textbooks. Just practical harmony that serves your story. We teach the few concepts you actually use on session day. Key equals a home base for notes. Scale equals the pool you fish melodies from. Chord progression equals the emotional runway under your lyric. We explain major, minor, and modes as mood sliders with bite size ear training. You will learn cadences which are endings that feel finished, turnarounds that reset the loop, and modulations that lift a chorus without fireworks. We map melody to chord tones so your topline lands like destiny. Real life example. Your verse feels flat. We swap one chord for its relative minor, add a passing chord, and give your pre chorus two bar tension so the chorus explodes. Theory that listens to feelings.
