The Score for Animal Voices is a multilevel elaborate project based on co-operation of many environments. Several dozen people participate in the execution of Elżbieta Jabłońska’s conception. Their involvement and dialogue between them is the basis for the creative process. It serves as experimental space for the author and it is equivalent with the planned final result. The documentation, in the form of audio and visual recordings, gathered during the project constitutes the starting material for the creation of the final form of the hybrid installation. Registered and compiled animal rumblings, humming, howling, squealing and whining became a prototype for the composer, conductor and choir members invited to participate in the project. Wojtek Kotwicki, a musician working in the project, registered the sounds of animals living in the zoological garden in Bydgoszcz. The score created by the composer Marcin Gumiela is an attempt to translate these sounds into the language of musical notation. The score is a kind of inspiration and working on it assumes a possibility of interpretation by the conductor Agnieszka Sowa and the members of the Academic Choir of the University of Science and Technology in Bydgoszcz.
