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.

What is claimed is: 1. A hybrid whistle having both a pealess chamber and a pea chamber, comprising: a mouthpiece with a left air opening, a central air opening and a right air opening; a left pealess whistle, comprising a left air passageway extending from the left air opening to a left air whistle chamber having a left air exit vent, wherein air flows from the left air opening through the left air passageway into the left air chamber and then exits the left air exit vent when the hybrid whistle is blown, thus creating a left whistle pitch sound; a right pealess whistle, comprising a right air passageway extending from the right air opening to a right air whistle chamber having a right air exit vent, wherein air flows from the right air opening through the right air passageway into the right air chamber and then exits the right air exit vent when the hybrid whistle is blown, thus creating a right whistle pitch sound; and a central pea whistle, comprising: a central whistle barrel chamber having a central exit vent, a pea block and a pea contained but movable within the central whistle chamber; and a central air passageway extending from the central air opening to the central whistle barrel chamber; wherein air flows from the central air opening through the central air passageway into the central whistle barrel chamber causing the pea to circulate within the central whistle barrel chamber and then exits the central air exit vent when the hybrid whistle is blown, thus creating a central whistle pitch sound; and wherein the pea block is formed within the central whistle barrel chamber so as to modify the barrel shape of the chamber and block 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; wherein the mouthpiece, the left pealess whistle, the right pealess whistle and the central pea whistle are integrally formed together with the central pea whistle being located between the left and the right pealess whistles; wherein the left air exit vent is substantially 180 degrees opposite the right air exit vent along a plane formed perpendicularly through the central air passageway, the left air passageway and the right air passageway; and wherein the central exit vent is substantially 90 degrees away from both the left air exit vent and the right air exit vent along the plane. 2. The whistle of claim 1, wherein the left and the right whistle pitches are of a first and second pitch and the central whistle pitch is of a third pitch causing tones to beat against each other. 3. The whistle of claim 2, wherein the first and second pitches are both higher than the third pitch. 4. The whistle of claim 1, wherein the mouthpiece has a concave shape. 5. The whistle of claim 1, wherein the pea is comprised of a synthetic cork material. 6. The whistle of claim 1, further comprising: a rubber overmolding fitted to the mouthpiece. 7. The whistle of claim 1, further comprising: a recessed logo space molded in the whistle at a location distant from the mouthpiece on a top planar portion of the whistle. 8. The whistle of claim 7, further comprising an insert fitted to the logo space. 9. The whistle of claim 8, further comprising a bezel that encases the insert in the logo space. 10. The whistle of claim 7, further comprising: a key-ring hole that runs through the whistle and the insert. 11. The whistle of claim 7, further comprising: a molded underside cavity in the whistle at a second location distant from the mouthpiece on a bottom planar portion of the whistle. 12. The whistle of claim 7, further comprising a bottom insert that is fitted into and held within a molded underside cavity. 13. The whistle of claim 12, wherein the bottom insert is selected from the group comprising: a compass, a thermometer, a flashlight and a second insert containing printed subject matter. 14. The whistle of claim 1, wherein the mouthpiece, the left pealess whistle, the right pealess whistle and the central pea whistle are integrally formed together from a two piece mold construction having a top portion and a bottom portion. 15. The whistle of claim 1, further comprising a second pea whistle, comprising: a second pea whistle barrel chamber having a second central exit vent, a second pea block and a second pea contained but movable within the second pea whistle chamber; and a second pea air passageway extending from the second pea air opening to the second pea whistle barrel chamber; wherein air flows from the second pea air opening through the second pea air passageway into the second pea whistle barrel chamber causing the second pea to circulate within the second pea whistle barrel chamber and then exits the second pea air exit vent when the hybrid whistle is blown, thus creating a second pea whistle pitch sound; and wherein the second pea block is formed within the second pea whistle barrel chamber so as to modify the barrel shape of the second pea chamber and block the air flow as the peas 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 thus creating a second pea whistle pitch sound. 16. A hybrid whistle having both a pealess chamber and a pea chamber, comprising: a mouthpiece with a left air opening, a central air opening and a right air opening; a left whistle, comprising a left air passageway extending from the left air opening to a left air whistle chamber having a left air exit vent, wherein air flows from the left air opening through the left air passageway into the left air chamber and then exits the left air exit vent when the hybrid whistle is blown, thus creating a left whistle pitch sound; a right whistle, comprising a right air passageway extending from the right air opening to a right air whistle chamber having a right air exit vent, wherein air flows from the right air opening through the right air passageway into the right air chamber and then exits the right air exit vent when the hybrid whistle is blown, thus creating a right whistle pitch sound; and a central whistle, comprising a central air passageway extending from the central air opening to a central whistle chamber; wherein air flows from the central air opening through the central air passageway into the central whistle barrel chamber and then exits the central air exit vent when the hybrid whistle is blown, thus creating a central whistle pitch sound; wherein at least one of the left whistle, the right whistle and the central whistle is a pea whistle and at least one of the left whistle, the right whistle and the central whistle is a pealess whistle; wherein the mouthpiece, the left whistle, the right whistle and the central whistle are integrally formed together with the central whistle being located between the left and the right whistles; wherein the left whistle pitch sound, the right whistle pitch sound and the central whistle pitch sound are all different; and wherein the left air exit vent is at a first angle directed away from the central exit vent in a plane formed perpendicularly through the central air passageway, the left air passageway and the right air passageway while the right exit vent is at a second angle directed away from the central exit vent in the plane. 17. The whistle of claim 16, wherein both the first angle and the second angle are between approximately 15 degrees and approximately 120 degrees. 18. The whistle of claim 16, wherein the mouthpiece, the left whistle, the right whistle and the central whistle are integrally formed together from a two piece mold construction having a top portion and a bottom portion.
