The invention relates to a wind instrument comprising a basic body in which extends a central duct which is bounded by a peripheral wall of the basic body, a plurality of openings in the peripheral wall which connect the duct with the surrounding air, a plurality of valves mounted on the basic body and each comprising a closure member co-acting with an opening and comprising control means connected to said valves. The control means guide the closure member for movement between a closed position in which the opening is closed by the closure member and an open position in which the opening is left clear. The closure member comprises a plate of stiff material which is provided on the side facing toward the opening with sealing material and which in the closed position engages sealingly around the opening. The closure member is connected to the control means by yieldable means.
