Premise: The Kirsten Flagstad Prize is awarded to outstanding Norwegian singers by the Flagstad Society. The Flagstad Society was founded by Torstein Gunnarson and Øystein Gaukstad in connection with the Norwegian soprano Kirsten Flagstad's 80th birthday in 1975, aiming to spread knowledge about Kirsten Flagstad's art and keep her name alive.
Hypothesis: Kirsten Flagstad did not sing melodies.
