Choir
Choir is a musical ensemble exercise in which the group creates a spontaneous vocal piece by layering sounds, harmonies, rhythms, and textures without a predetermined plan. A designated conductor guides the group's dynamics, bringing individual voices in and out, adjusting volume, and shaping the overall sound. The exercise builds musical listening, ensemble sensitivity, willingness to contribute individual sounds to a collective creation, and comfort with creating in the moment. Choir demonstrates that a group of non-musicians can produce complex, textured sound when each member commits to listening and responding to the whole rather than focusing on individual performance.
Structure
Players stand in a semi-circle facing a designated conductor. The conductor explains the basic hand signals: palm up and rising means increase volume, palm down and lowering means decrease, a pointed finger brings in a specific player or section, and a closed fist cuts a section off entirely.
The conductor points to a single player, who begins producing any sustained sound: a hum, a vowel, a rhythmic pattern, a percussive noise. The conductor then brings in a second player, who adds a complementary sound that fits with but differs from the first.
Sounds are layered gradually. The conductor controls the pace of additions, allowing each new voice to find its place within the existing texture before introducing the next. The conductor shapes the piece by adjusting volume, bringing sections in and out, and building toward dynamic peaks and valleys.
As the piece develops, the conductor experiments with contrast: bringing the full choir to a crescendo, then cutting all voices except one, then rebuilding from that single thread. The exercise concludes when the conductor brings the piece to a deliberate close, either through a gradual fade or a sharp cutoff.
How to Teach It
How to Explain It
"We are a choir. When I raise my hand, we sing. When I lower it, we stop. Sing anything: a song, a melody, sounds. Match the people around you. Listen more than you sing."
The biggest barrier to this exercise is self-consciousness about singing or making sounds in front of others. Begin by establishing that no musical ability is required. The exercise uses voice as an instrument for texture and rhythm, not melody or pitch accuracy.
Coach the conductor to build the soundscape slowly. Bringing in too many voices too quickly produces a wall of undifferentiated noise rather than a layered composition. Each new addition should be audible and distinct before the next voice enters.
Players tend to default to safe, quiet sounds. Encourage variety: whispered consonants, rhythmic clicks, sustained vowels, animal sounds, guttural drones. The more diverse the individual contributions, the richer the collective texture.
A common pitfall is players listening only to their own sound rather than to the group. Coach players to adjust their volume, pitch, and rhythm in response to what they hear around them. The exercise functions when each voice serves the whole rather than competing for attention.
For groups with strong musical skills, add a variation in which the conductor steps out and the group self-conducts, responding to each other without external direction. This advanced version builds the ensemble listening skills directly applicable to group scenes in performance.

Related Exercises
Orchestra
Orchestra is a group exercise in which players create a collective musical composition using voices, body percussion, and physical gesture. A conductor cues volume, tempo, solo moments, and ensemble dynamics. The exercise trains ensemble responsiveness, collective listening, and the ability to follow and surrender to shared direction without losing individual contribution.
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.
Xylophone
Xylophone is a musical exercise in which the group creates a human xylophone by assigning each player a different note or sound. A conductor plays the ensemble by pointing to individual players, creating improvised melodies and rhythms. The exercise trains responsiveness, musical awareness, and the ability to contribute a precise element to a group composition.
Three Melodies
Three Melodies is a musical exercise in which performers learn and layer three distinct melodies simultaneously, building a group composition from separate musical lines. The exercise trains musical listening, the ability to maintain an individual part within a group, and the awareness of how separate elements combine into harmony.
Sound Follow
Sound Follow is an exercise in which one player creates a continuous vocal sound and the rest of the group attempts to match and follow it as precisely as possible. The leading sound may change gradually in pitch, rhythm, or quality. The exercise trains group listening and the ability to attune to subtle shifts in shared vocal production.
Crescendo
Crescendo is a group energy exercise in which the ensemble gradually builds sound, movement, or emotional intensity from complete stillness to a peak, then releases back to silence. The exercise trains dynamic control, group sensitivity, and the ability to ride a shared wave of energy without any single player driving the escalation. Crescendo demonstrates the dramatic power of collective escalation and release, teaching performers that the contrast between quiet and loud, stillness and movement, creates more impact than sustained high energy alone.
