Circle Song

One person gives out repeating parts to the groups.

Find parts by first singing what’s inside, then refining to find a motor part. Harmony is good. Look for spaces in the motor part to interlock new parts.

Find parts by first solo-ing over what is already created.
Play with rhythm – try putting 3 over 4 or try something in an odd rhythm like 5/4, 7/8, 9/8
Play with tonality – use some unusual harmonies, try notes that may not be the “first choices”
Play with language – try using some sounds you don’t always use; experiment with different consonants; imagine you’re speaking a language you don’t know but have a sound in your ear eg. french, russian, italian, etc.

The person giving out the parts can then solo over the foundation they have created.

Solo-ist can then step out and let another person solo and/or create new parts…

One person creates a short phrase (use name, a word, or made up sound) with voice and body. Group echoes it back, vocally and physically. Take turns going around the circle.

With this exercise, we are able to go places with our voices and bodies that aren’t our usual habits. We have the opportunity to see what it feels like to sound like and move like other people, and get new vocal and physical ideas from them.
