Whistle with finger grip

A whistle for producing resonant frequencies comprising:

• a) a body includes a mouth piece having an inlet, at least two sound chambers to which inlet air is blown from the inlet,
• b) air passageways for communicating inlet air from the inlet to the sound chambers;
• c) the body further includes at least two exhaust ports in communication with the sound chambers for discharging air and sound;
• d) a finger grip which includes a contiguous finger sleeve integrally connected to the body for receiving and surrounding two fingers therein;
• e) the finger sleeve includes a V shaped expansion spring for accommodating variations in finger size and gripping the fingers within the finger sleeve, the V shaped expansion spring moveable between a normal V position and an expanded position wherein the V shaped spring is substantially flat.

A whistle for producing resonant frequencies comprising:

• a) a body includes a mouth piece having an inlet, at least two sound chambers to which inlet air is blown from the inlet;
• b) air passageways for communicating inlet air from the inlet to the sound box and sound chambers;
• c) the body further includes at least two exhaust ports in communication with the sound chambers for discharging air and sound;
• d) wherein the two sound chambers are dimensioned to create peak principal frequencies which interactively produce a pulsating sound having a periodic pulse frequency of less than 0.1 KHz.
