Marian Anderson's Hair Pins

Origin
Marian Anderson was one of the most celebrated singers of the twentieth century, performing venues in the United States and Europe alongside famous orchestras. When she was denied admittance to sing for an integrated audience in Constitution Hall, she was catapulted into the public spotlight. With the support of First Lady Eleanor Roosevelt, Anderson performed an open-air concert on Easter Sunday on the steps of the Lincoln Memorial. She sang before a crowd of more than 75,000 people and a radio audience in the millions. Anderson continued to break barriers for black artists in the United States, becoming the first black person, American or otherwise, to perform at the Metropolitan Opera in New York City.

Effects
Fine tunes the wearer's voice to have a pitch so perfect that they can destabilize surrounding structures when vocalizing.
