The term originated during the swing era of dancing, probably borrowed or appeared in parallel with the expression "jam session" in music. Scenes with jamming may be seen in movies and musicals, such as Hellzapoppin. At the same time, this kind of dance behavior is not unusual in folk dances in various cultures all over the world and is often included in scenic performances when a group dance is interweaved with several solos. In Lindy hop, it is common for jam circles to take place on or around special occasions such as birthdays or weddings.
