Elmo the Musical is a Sesame Street segment that began airing in the 43rd season. The segment was featured in every episode until season 46, where it alternated with "Elmo's World." In each eleven-minute segment, Elmo teaches math skills while imagining himself in different musical situations, such as "Sea Captain the Musical," "Mountain Climber the Musical," "Prince Elmo the Musical" and "President the Musical." Joining Elmo in his adventures is Velvet, a talking set of curtains, and a series of animal and Anything Muppet friends (see ). __TOC__
