Machine
Machine is a group exercise in which one player starts a repeating movement and sound, and the rest of the group joins one at a time until the ensemble becomes one interlocking human machine. Each new part has to connect to what is already happening instead of operating as a separate solo. The exercise trains timing, ensemble awareness, physical commitment, and the habit of building something together in full view of the room.
The Machine

Each new contributor must connect their action to the existing mechanism. The exercise develops ensemble coordination, physical commitment, and the ability to contribute to a shared creation.
Growing and Shrinking Machine
Growing and Shrinking Machine is a group exercise in which players build a human machine of interconnected sounds and movements, then the machine grows as players join one at a time and shrinks as they leave. The facilitator may control the speed, intensity, or emotion of the machine. The exercise trains ensemble coordination and the ability to contribute a complementary part to a group creation.
Machines

Sound Circle
Sound Circle is an exercise in which players stand in a circle and build a collective soundscape, with each person contributing a unique vocal sound that layers into a group composition. A conductor may direct the volume, tempo, and texture of the ensemble. The exercise develops group listening, vocal range, and the ability to contribute to a shared creation.
Heave Ho
Heave Ho is a group energy exercise in which players build shared physical momentum through synchronized movement and vocal sounds, working toward a collective release. The group rocks or sways together, building rhythmic energy through a repeated "heave" motion, until a shared peak is reached and the group releases with "ho." The exercise builds group synchrony, physical awareness of collective rhythm, and the experience of shared energy building to a shared release.
