A hybrid whistle has two pealess whistle chambers with air vents to the left and right and a central pea whistle with an air vent facing generally perpendicularly to the left and right air vents that are integrally formed together, preferably in a two piece, top and bottom, construction. The hybrid whistle has a mouthpiece with a left air opening, a central air opening and a right air opening, each of which is connected to its respective whistle chamber by an air passageway. The three whistle chambers produce differing whistle pitch sounds as air flows through them and out the chambers' exits. The central pea whistle has a barrel chamber with a pea block formed within it so as to modify the barrel shape of the chamber and block the air flow as the pea circulates in the air current causing a staccato effect, while creating enough circulating air movement to prevent the pea from getting stuck in the vent by the air as it exits out of the central air exit when the whistle is blown. A second pea whistle can be added to the hybrid whistle.
