During the Musical Craft lessons, the basis is laid for the joint disciplines of Theatre Craft and Musical Theatre. Both are fun and varied dance styles dating from the 19th century and are often used in combination with theater shows and musicals. Ballet School de Kattensprong teaches according to the British style of Theatre Craft and Musical Theatre. Along with the United States, Britain has been a forerunner in the development of the musical genre. Examples of famous and iconic musicals that have appeared include West Side Story (1957), Les Misérables (1985), The Phantom of the Opera (1986) and Wicked (2003).
