Vocals is an episode of BrainPOP launched on August 26, 2006.
After Tim and Moby get back home from an opera, Tim pulls out a letter asking how singers 'belt their voices' loud. Tim then talks about vocals, and the different vocal ranges, as well as different kinds of vocal music. Afterwards, Moby has his own choir with other robots.
During the vibrato part (which was done using cut-out animation, like the show's early episodes), you can see some trash before the teenager is singing.
