A whistle mouthpiece is provided that has a whistle mechanism that comprises one or more openings that may contain one or more reeds or other frequency producing mechanisms that produce the same or different resonant frequencies. The one or more openings may transversely cross the whistle mouthpiece in a parallel manner, or may alternatively exit the whistle mouthpiece at the front portion at a non-parallel location or at another location along the bottom or top of the mouthpiece.
