The LCAN SB3 (Live Coding Animated Notation in a Shared Browser-Based Buffer) was designed to create a functionalrelationship between two seemingly disparate fields of practice: live-coding and animated notation. While these twofields are both representative of the artist-programmer ethos, their differences lie in their respective purposes. Withlive-coding the artist-programmer writes and executes code in real time with a variety of audio and visual resultsin traditional and non-traditional performance environments. Animated notation, like traditional notation, requires aspecific symbol system, designed by the artist-programmer, which indicates to human performers what musical event(s)to execute and when. The result of this relationship is akin to a traditional performance environment, yet there is adivide between the composer (artist-programmer) and the musical result by way of the performers. The author’s LCANSB3 seeks to merge these two fields by providing a platform by which the artist-programmer can live-code animatednotations in real time that can then be performed by one or more performers. The LCAN SB3 also provides supportfor a shared browser-based buffer system in which two or more artist-programmers can create animated notation inreal time regardless of location, enabling the creation and presentation of the resultant animated score at one or moreremote sites.
