The pku (also known as pzuk) and the blul are traditional Armenian wind instruments, belonging to the family of aerophones with single reed or fipple design.
Often compared to the clarinet, the pku is known for its direct and expressive tone, while the blul, a pastoral flute, offers a softer and more meditative sound.
Deeply rooted in the musical heritage of Armenia, these instruments play an important role in traditional repertoire, combining melodic simplicity with strong emotional expression.
