Said apparatus uses a rotary pulse generator to create musical tones when in contact with the rotating platter of the turntable. Said apparatus mounts to the turntable in such a way that a rotary pulse generator rotates when in contact with the rotating turntable platter. As the radius at which the rotary pulse generator contacts the turntable platter is increased the frequency of the tone produced increases proportionally, likewise when the radius at which the rotary pulse generator contacts the turntable platter is decreased the frequency of the tone produced decreases proportionally allowing a range of pitches to be sounded."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Apparatus for varying the pitch of audible tones driven by a turntable","description":"A musical instrument adapted for use with a turntable.
