its own systems of notation, and was a student of the Schillinger System, which almost exclusively used graph methods for describing music. From this perspective FOLIO was an inspired, yet logical connection to be made—especially for a Northeasterner who grew up playing and improvising jazz. December 1952 consists purely of horizontal and vertical lines varying in width, spread out over the page; it is a landmark piece in the history of graphic notation of music. The role of the performer is to interpret the score visually and translate the graphical information to music. In Brown's notes on the work he even suggests that one consider this 2D space as 3D and imagine moving through it. The other pieces in the collection are not as abstract. According to dates on the scores, Brown wrote December 1952 and then moved back towards forms of notation that contain more specific musical information.
