The invention discloses a double-hole kazoo which comprises a first resonance tube and a second resonance tube. An outer annular boss is arranged on the outer circle of the tail of the first resonance tube, an inner annular boss corresponding to the outer annular boss is arranged at the inner circle of the head of the second resonance tube, and the inner annular boss and the outer annular boss are connected in an inserting mode and fixed in an adhering mode through a power adhesive; a first membrane hole and a second membrane hole are formed in the upper end of the first resonance tube and the upper end of the second resonance tube respectively, and the inner diameter of the first membrane hole is larger than that of the second membrane hole; the first resonance tube and the second resonance tube are each formed by combining two different materials of rigid plastics, metal and wood. When a solo is played through the double-hole kazoo, the ideal sound effect equivalent to the instrumental ensemble effect through two kazoos made of different materials can be generated.
