A fugue is a type of musical composition characterized by the systematic interweaving of multiple melodies, known as voices. It typically begins with a single voice presenting a main theme, called the subject, which is then imitated by other voices in succession. This technique creates a rich tapestry of sound, showcasing the composer’s skill in developing and manipulating musical ideas. Fugues are often associated with the works of composers like Johann Sebastian Bach, who mastered the form. They can be found in various musical genres, including classical and contemporary music, and are valued for their complexity and structural integrity.
