A person who writes or composes fugues; a fugal composer.
From 'fug-' (relating to fugues) plus '-ard' suffix (one who practices or is associated with something). A rare or archaic term.
This is an almost extinct word—we mostly just say 'composer' now, but it shows how English once had specific words for specialists in different musical forms, like how we still say 'symphonist.'
