Email me, LorenGro...@gmail.com to register for the Underscore or the Talk Through. This Underscore will only happen if there are at least 5 positive RSVPs by 1pm on Friday 10/10/25.

WHY: A prior Talk Through is required to participate in the Underscore.

The Talk Through also provides a common language and glyphs (symbols) to use when reflecting on our practice in the concluding Thanksgiving and Harvest.

NOTE: This Underscore will only happen if at least 5 people RSVP positively by 9pm on Thursday 10/9.


WHAT IS THE UNDERSCORE?

The Underscore Practice is a simple and beautiful structure for a focused jam-like practice developed by Nancy Stark Smith. The structure is a precise, but open platform for investigation of contact improvisation and solo and group improvised composition. The score is an organic developmental nonverbal sequence that provides focus to the dancing community and opens up possibilities for movement, awareness, connection, and various physical/mental states. We (do our best to) commit to participating in the entire score (which includes resting, eating, digesting, observing, bonding with the earth).

Nancy Stark Smith, who originated the practice, describes it this way: "The Underscore is a vehicle for incorporating Contact Improvisation into a broader arena of improvisational dance practice; for 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." More info: http://nancystarksmith.com/underscore


UNDERSCORE PROTOCOL:

The Underscore is a carefully held container and an intentional space. This is NOT a come and go jam. We aim to commit to the entire practice together. Those who Arrive at 2:30pm and come to the Assembly shortly thereafter should plan to stay through the conclusion by 5:30pm as it is customary to commit to the full session for an Underscore Practice. Building doors open at 2:15 for arriving.

YOU MUST REGISTER by emailing LorenGro...@gmail.com Capacity is 15, first come first serve. I will post on the Ci Philly listserv if we have moved into a waiting list.

A prior UNDERSCORE TALK THROUGH is required to participate in the Underscore. More about this below.

Street shoes and Food are NOT permitted in the dance studios. If you need to wear shoes to dance, they should be soft soled, clean, and not worn outside. You may snack in the lounge or outside.

I recommend bringing a water bottle, snacks, something to write on, and something to write with.


HEALTH /COMMUNITY CARE PROTOCOL:

Capacity is limited to 15 people.

I strongly encourage you to wash your hands once you arrive to the building and after the Underscore before you leave.

Masking varies between REQUIRED and OPTIONAL. Masking is OPTIONAL for 10/11/2025.

Touch with consent is permitted.

I am prepared to do contact tracing. If a participant discovers within 7 days after the Underscore that they are positive for covid, monkeypox or another infectious disease that could have transmission in the Underscore setting, please email lorengro...@gmail.com and we will let the rest of the group know about their possible exposure.

Since September 2022, Covid-19 Vaccination is encouraged, but not required.

Generally, I strongly encourage all participants to wear clean garments with long sleeves and pants for minimal skin exposure. However, it is summer, so dress as you need to feel comfortable for your dancing. Please know there is air conditioning in the space.

Do NOT attend the Underscore if you have symptoms of COVID, have tested positive for COVID or have a known or possible COVID exposure in the last 10 days, UNLESS you have tested negative at least 5 days after exposure.

Do NOT attend the jam if you have symptoms of Monkeypox Virus (flu, fever, swollen lymph nodes, new skin rash), a current case of MPV, or a known exposure to MonkeyPox in the past 2 weeks.

The Underscore Practice is a simple and beautiful structure for a focused jam-like practice developed by Nancy Stark Smith. The structure is a precise, but open platform for investigation of contact improvisation and solo and group improvised composition. The score is an organic developmental nonverbal sequence that provides focus to the dancing community and opens up possibilities for movement, awareness, connection, and various physical/mental states. We (do our best to) commit to participating in the entire score (which includes resting, eating, digesting, observing, bonding with the earth).

Nancy Stark Smith, who originated the practice, describes it this way: "The Underscore is a vehicle for incorporating Contact Improvisation into a broader arena of improvisational dance practice; for 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."

UNDERSCORE PROTOCOL:

The Underscore is a carefully held container and an intentional space. This is NOT a come and go jam. We aim to commit to the entire practice together. Those who Arrive at 4:00pm and come to the Assembly shortly thereafter should plan to stay through the conclusion by 6:00pm as it is customary to commit to the full session for an Underscore Practice. Building doors open at 3:45 for arriving.

YOU MUST REGISTER by emailing LorenGro...@gmail.com Capacity is 15, first come first serve. I will post on the Ci Philly listserv if we have moved into a waiting list.

A prior UNDERSCORE TALK THROUGH is required to participate in the Underscore. More about this below.

Street shoes and Food are NOT permitted in the dance studios. If you need to wear shoes to dance, they should be soft soled, clean, and not worn outside. You may snack in the lounge or outside.

I recommend bringing a water bottle, snacks, something to write on, and something to write with.


HEALTH /COMMUNITY CARE PROTOCOL:

Capacity is limited to 15 people.

I strongly encourage you to wash your hands once you arrive to the building and after the Underscore before you leave.

Masking varies between REQUIRED and OPTIONAL. Masking is OPTIONAL for 12/6/2025.


Touch with consent is permitted.

I am prepared to do contact tracing. If a participant discovers within 7 days after the Underscore that they are positive for covid, monkeypox or another infectious disease that could have transmission in the Underscore setting, please email lorengro...@gmail.com and we will let the rest of the group know about their possible exposure.

Since September 2022, Covid-19 Vaccination is encouraged, but not required.

Generally, I strongly encourage all participants to wear clean garments with long sleeves and pants for minimal skin exposure. However, it is summer, so dress as you need to feel comfortable for your dancing. Please know there is air conditioning in the space.

Do NOT attend the Underscore if you have symptoms of COVID, have tested positive for COVID or have a known or possible COVID exposure in the last 10 days, UNLESS you have tested negative at least 5 days after exposure.
