Shrink the major third by a semitone and the same stable shape turns melancholy. A minor triad still resolves, it just carries a heavier, more introspective mood than its major counterpart. Sad songs lean on it constantly, but so do tense film cues and moody grooves, so treat the label as a starting point rather than the whole story.
