The Underscore, a long-form dance improvisation structure created by Nancy Stark Smith, incorporates Contact Improvisation (CI) into the broader arena of improvisational dance practice. Global Underscore (GUS) centers around a yearly event in which the Underscore is practiced simultaneously for a 4-hour period by people all over the world near the summer solstice (northern hemisphere).

70+ sites participate in GUS.

The Underscore, which has been evolving since 1990, is a vehicle for incorporating Contact Improvisation (CI) into the broader arena of improvisational dance practice; developing greater ease dancing in spherical space—alone and with others; and for integrating kinesthetic and compositional concerns while improvising. It allows for a full spectrum of energetic and physical expressions, embodying a range of forms and changing states. Its practice is familiar yet unpredictable.

The practice progresses through a broad range of dynamic states, including long periods of very small, private, and quiet internal activity and other times of higher energy and interactive dancing.

There are 20+ phases, 12+ connections, and 7 aspects of the Underscore—each with a name and a graphic symbol—which create a general map for the dancers. Within that frame, dancers are free to create their own movements, dynamics, and relationships—with themselves, each other, the group, the music, and the environment. Each Underscore is unique, providing rich and often inspiring experiences of the human and artistic phenomena of dance improvisation.

Near the beginning and at the end of the Global Underscore practice, dancers at each site do the Stand/Small Dance (a focus on standing developed by Steve Paxton) together facing the next site around the globe, making an energetic line that spirals around the earth. These are called the Facings.

It is important that one does a “Talk-Through” of the Underscore, which often takes about an hour, before dancing the Underscore. The Underscore is generally not led with verbal cues; the idea is that people “know” it already and are coming together to share the practice. Participants come on time and stay for the duration of the event.

There are several Options for Participation in the Global Underscore, so a dancer or GUS Site facilitator can choose whichever level of involvement they want.

GUS organizes these yearly events:  (2023 GUS Events)

  • In-Depth Talk-Through (on Zoom) of the Underscore: by many teachers from across the world, discussing the Phases, Connections, and Aspects of the Underscore.
  • GUS Practice (the main event): supporting 70+ GUS sites around the world dancing (mostly simultaneously) a 4-hour Underscore.
  • “Catch-All” Zoom:  The “Catch-All” is a virtual GUS Site, for both individuals and other GUS Sites, during the GUS practice time.
  • Meta-Sharing (on Zoom): sharings from the GUS practice, Underscore discussion, Underscore visions/ideas, and Nancy Stark Smith teachings — with some movement/embodied time.

The GUS Store sells Mike Vargas’ 86 Aspects of Composition Cards. In addition, GUS also supports the development of the Underscore, Contact Improvisation, Contact Quarterly (CQ), and the legacy of Nancy Stark Smith.
