Retro Psychedelic

Why it sounds this way

Retro Psychedelic is a dark chord progression that moves vi7 – ♭vii7 – ♭VImaj7 – V7 (Am7 B♭m7 A♭maj7 G7 in C). The feeling walks longing · mellow → rebel · mellow → gaze up · glow → tension · poised. The extra quality words (mellow, glow, poised) are why the colors soften or spark: sevenths and sus chords never quite say the feeling in a straight line. That matches a small tip for this mood: flat chords pull the floor away. That is why it fits a scene like “a jukebox in an empty diner.” Play it on piano or guitar above, and switch keys if you want it higher or lower.
