Abstract
Although numerous digital tools exist to support the capture and editing of music, less attention has been paid to supporting the creative process of music composition. In this paper we report the design of a new tool in this area, targeted specifically at collaborative composition between a composer and one or more performers. The tool is an open source ‘composer’s notebook’ app called Com-Note, which supports the creation and exchange of multimedia narratives on an Android smart phone. Requirements for the design of Com-Note were derived in a case study of the collaborative composition process, as assisted by a digital storytelling app called Com-Phone developed on another project. This involved the creation and performance of a new work for trumpet and string quartet entitled Albumleaves.
