This video shows a larynx with a hemorrhagic (blood filled, aka vascular) polyp on the right vocal fold. The polyp results in incomplete closure of the glottis, and irregular vibration of the vocal folds. The varies according to pitch and loudness. The video makes it clear why the singing voice quality in the audio clip varies from markedly rough to normal.
