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.
Structure
Setup
- Each player is assigned a distinct sound: a note, a syllable, a word, or a non-verbal sound.
- Players arrange themselves in a line or semi-circle, physically representing the layout of the instrument.
- A conductor stands in front of the group.
The Instrument Plays
- The conductor points to individual players, who produce their assigned sound precisely when indicated.
- The conductor can point rapidly or hold the indication for sustained sounds.
- Players who are not indicated stay silent.
- The conductor creates improvised melodies, rhythms, and sound patterns using the ensemble.
What the Exercise Trains
- Precision: each player produces only their sound, only when indicated, and stops when the indication is removed.
- Ensemble listening: the group must hear the pattern the conductor is creating and contribute to it precisely.
- Responsiveness: the player must be ready at any moment for the conductor to return to them.
Variations
- Multiple conductors take turns, each creating a different musical section.
- Players can be reassigned sounds mid-exercise by the conductor.
- The ensemble creates a complete improvised piece with a beginning, development, and ending.
How to Teach It
How to Explain It
"Each of you is one note in this instrument. You play exactly when I point to you and stop exactly when I stop pointing. Not before, not after. My pointing hand makes the music. Your job is to be the instrument."
Common Notes
- Players who sound before the point or after the release blur the musical precision. Crispness of onset and release is part of the exercise.
- The conductor should begin with simple, clear patterns before attempting complex rhythms. The ensemble needs to calibrate before the music can develop.
- The ensemble's listening quality is visible in the tightness of the response. An ensemble with good group attention responds almost simultaneously with the point.
Common Pitfalls
- Players anticipate the conductor's point and sound before it arrives. The point triggers the sound; anticipation undermines the precision.
- The conductor tries to create too complex a piece before the ensemble has established basic responsiveness.
- Players who have not been pointed to recently lose focus and miss their entrance when the conductor returns to them.

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.
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.
Underscore
Underscore is a scene exercise in which a live musician provides continuous music beneath an improvised scene, offering an emotional layer that performers can follow, play against, or let shape their choices. The exercise trains sensitivity to nonverbal emotional cues and builds the habit of receiving external offers from non-human sources. It is a standard element of improv training that uses live or recorded sound as an environmental collaborator.
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.
Conducted Story
Conducted Story is a performance game and exercise in which a conductor points to different performers in a line, each of whom must continue a collaborative story from exactly where the previous speaker stopped. The conductor controls pacing, speaker changes, and dramatic rhythm by pointing rapidly or slowly between performers. Switches can occur mid-sentence, mid-word, or at natural pauses, forcing performers to listen with total attention and maintain narrative coherence under pressure. As noted in Truth in Comedy, Conducted Story is one of the foundational exercises for developing the ability to stay in the moment rather than planning ahead.
