Technology has changed the music industry. Instead of purchasing music by the album at a music store, consumers can download songs at any time, from almost anywhere on the planet. This means new options for the music that we use in class.

Traditionally, classes in the group exercise room have been taught to specially formatted "cardio" music. Instructors teach a couple of movements to an 8 count phrase. Four phrases are combined to make 32 count blocks. The music changes every 32 counts, making the start and stop of a choreography block recognizable and predictable.

But now that we can burn a CD to suite our needs, we are not chained to the music on a pre-purchased CD. We can use music that moves us to create more exciting, challenging classes with simple choreography.
