This is perhaps the most common type of flash mob that takes place and often creates the biggest spectacle.

1. 1 Choose a song. Do you want it to be something up-tempo or more mellow? Do you want something well known or something that displays a certain style of music, such as opera?
2. 2 Find someone able to choreograph. If this is you, great. If not, get someone who knows how to help turn a group dance into something spectacular.
3. 3 Choose your spot for the dance. A park in a major city is a great spot, especially during lunch hour or after work when everyone is heading home.
4. 4 Gather a group of dancers. Flash mob dances can be any number of people but try to aim for at least 50-75. It may sound like a lot to arrange but the more people you have, the more effective the flash mob dance becomes.
5. 5 Teach them all the dance in smaller groups of 4-30. This way you don't have to get too many people in the same room or area at once and they can also entertain the crowd from different perspectives. This is good for people who can't see the whole scene in front of them.
6. 6 Choose a flash mob leader. This will be the best dancer in the group, the person who sets the beat and provides a following point for the remaining dancers. The leader can start the routine with a solo dance move, then attract the next group of 9 to 15 dancers who join in with the next move. Then, double the group's size with 16 to 30 dancers joining in. The trick to a good flash mob is to gradually get all of the dancers involved in the routine. Get the rest of them to join in in the last part of the song so that the entire group is finally involved.
7. 7 Pretend as if nothing has happened. As soon as the song has finished, the dancers must disperse as normal members of the crowd to act as if nothing has happened.
