Mournful is a sad chord progression that moves iii – vi – vii° – III (Em Am Bdim E in C). The feeling walks wistful → longing → edge → pull. Most of these are plain triads, so the colors feel direct and the outline stays clear. That matches a small tip for this mood: minor chords lean on blue. That is why it fits a scene like “moonlit lament.” Play it on piano or guitar above, and switch keys if you want it higher or lower.
