The Rise of Large K-Pop Groups
K-pop’s history has seen an evolution in group sizes, from small, tight-knit units to expansive teams with complex dynamics. Large groups often bring a variety of advantages:
-
Diverse talents – More members mean a wider range of skills, from powerhouse vocals to expert choreography.
-
Unit concepts – Subunits within a group allow different musical styles to shine.
