Looking at the broad terrain of Korean music, but with a focus on fusion, music critic and broadcaster Yun Chunggang (2004)has been so bold as to suggest that the 20th century was the kayagum century, but the 21st century is becoming the haegum century. (The 19th century was, he says, the komungo century.) New compositions for haegum have appeared in recent years more frequentl than previously, but most importantly haegum has become a mainstay in many fusion music groups.
