You are invited to a one-time online interactive improvisational movement and music event featuring musician Bruno Ferro Xavier da Silva in celebration of International Dance Day, as part of the Mission Improvable series and in collaboration with Contact Zone Rotterdam, in the Netherlands. 

4.45pm EDT (USA) or 22.45h CAT/CEST (Africa, Europe) – open space, gathering
5pm EDT                 or 23.00h CAT/CEST                           – start of the dance session (no further admission possible)
6.15pm EDT            or 00.15h CAT/CEST                           – optional aftertalk until 6.45 EDT / 00.45 CAT/CEST

We will use a “Score of the Day” (AKA “structure,” “framework,” or “procedure”) to support our creativity.
You will also be invited to take inspiration from the “Theme of the Day”.

Score of the Day:
An accumulation-deaccumulation score in one Zoom room.
Bruno is on equal footing with participating dancers, entering and leaving the “dance floor” by turning his Zoom camera on and making music, or turning his camera off and coming to silence.
We all use the “Hide non-video participants” Zoom feature, so that the “placeholders” for people with video cameras off are not visible on screen.

We begin in silence, with all cameras off (empty “floor” = empty screen).
Any person who feels the desire turns their camera on and begins.
As others feel the desire they turn on their cameras and join in in their own time.
That is the accumulation phase.

Then, at some point, one person who feels the desire to leave the “floor” turns off their camera, and others leave the floor in their own time (the deaccumulation phase), until the floor is empty again.

Then we begin another accumulation-deaccumulation cycle.
We aim for each accumulation-deaccumulation cycle to last between 2 minutes and 20 minutes.

Not everyone in the meeting would necessarily be on screen for any given cycle. For example, the accumulation may be short, and deaccumulation might start after only a few people have cameras on. Stay unmuted to allow the sounds of your dancing to be heard by others, unless there is excessive noise in your space. Use “Gallery View” to allow interaction with all present.

Theme of the Day “Invitation to Secret Dancers”:
Invitation to Secret Dancers was created 1973 by choreographer, intermedia-artist, somatic movement pioneer and co-founder of the original Judson Dance Theater, Elaine Summers. The dance invites anyone to come and dance together in any way they choose to do their dance at that moment.

Your Hosts:

Nancy Hughes

Since 2020 she has produced the weekly online Mission Improvable series.

Contact Zone Rotterdam / Thomas Körtvélyessy

Contact Zone Rotterdam is an ongoing project by Stichting Sanne in the Netherlands, which explores contact improvisation and its related aspects in workshops, courses and one-time events, promoting and further developing this dance form. Thomas is part of this team as an advisor. He has been working consistently on re-forming dance for the 21st century from the sensorial experience of movement. Director of Reàl Dance Company, he is interested in empowerment and liveliness in the moment of communication and studied for many years with Elaine Summers, including her somatic work Kinetic Awareness.

Zach Pine

Zach has been teaching contact improvisation since 2013 in California. Playfulness, curiosity, creativity, communication, and connection are at the heart of all Zach Pine’s work on and off the dance floor. Since 2020 he’s hosted the online weekly CI-Inspired Score & Jam: Beyond Saudade. He’s been lucky to learn from many teachers.
