Stroboscopy: Rigid: vocal slide down in female

This slide downward in pitch demonstrates how the vocal folds shorten in length to decrease pitch. The light is constant so the edges of the vocal folds blur during phonation. The video frame rate on this digital recording was 30 frames per second and the vocal folds are vibrating at over 200 vibrations per second. A rigid scope was used for the recording.
