  • Patent number: 4269104
    Abstract: A musical instrument of the woodwind type in combination with a raised oblong resonance chamber, said instrument configured in the shape of a human hand. The resonance feature is utilized by placing the oblong or blister-like protrusion against the cheek of a user which, when tapped on its opposite side achieves tonal variations as a function of size variation and degree of modulations of the oral cavity. The woodwind function is achieved by blowing through a mouthpiece (the thumb digit) and egress of wind passing through the fingerhole portions of the remaining four finger digits.
