The artistic challenge

Music inside the action.

The “Fight of 100” was fully choreographed to the score. The music needed to give the physical action rhythm, weight, and momentum within the larger dramatic world of the play.

My contribution

One connected sonic world.

I composed the original score and designed the production’s sound, bringing together beatboxing, electronics, cello, woodwinds, piano, and drums. The work moves from the force of combat to the stillness of mourning.

Hear the dramatic range.

The Fight of 100
Original score · 2:23

Listen for

How musical rhythm can organize physical action. Listen for changes in momentum, and consider how a choreographed fight can unfold through a score.

Beyond the score

The theatre becomes
part of the sound.

At selected moments, Cyrano’s amplified voice moved through the theatre, extending his presence beyond the stage and surrounding the audience.

Concealed floor microphones supported speech intelligibility where needed. Battle sequences and fight effects gave the war and combat scenes their sonic force.
