[1] The ride features organ music renditions of songs from films including: Sleeping Beauty, Snow White and the Seven Dwarfs, Mary Poppins, and other Disney movies.

The carousel was built by William Dentzel[2] and had been operated at Sunnyside Beach Park in Toronto, Ontario, since 1922;[2] it had three courses of horses and other animals on a platform 72 feet (22 m) in diameter.

The attraction was refurbished and significantly altered by the Arrow Development Company of Mountain View, California in preparation for opening day.

By opening, the ride consisted of 72 galloping steeds in 18 rows, all moving, in shades of brown, tan, grey, brownish red, black, and white.

In preparation for Disneyland's 50th anniversary celebration, the Happiest Homecoming on Earth, King Arthur Carrousel closed for extensive renovations and reopened in February 2003.

On the saddle flap, a decorative crest was added, with the monogram "JA", a bird perched on high button shoes, a silhouette of Mary in flight, and the number 50, representing the 50th anniversary of this original Disneyland attraction.

Jingles was then ceremoniously dedicated to Julie Andrews on April 8, 2008, as "Honorary Ambassador", the title painted beneath the Hidden Mickey on her cantle.
