13.0.0.0.0 Composed by Carlos Delgado for Timpani and Lev- performed by Peter Jarvis

13. 0. 0. 0. 0. for timpani, Lev, vocals and video was written for Peter Jarvis. Lev is a gestural-control program that takes the input of a video camera and assigns a range of values to specific areas of the camera's field of vision. These values can in turn be used to generate MIDI, audio, and video-control data. In this way, the performer can play sounds and manipulate video in real time though his movements in space.
The Maya based their calendrical system on a methodical study of the apparent movement of celestial objects such as Venus, the sun, the moon, and the Milky Way (the "Tree of Life"). They also developed the only full writing and numerical system in the Americas, which they used to record their observations in extremely accurate astronomical tables. These predicted, among other things, lunar eclipses and seasonal solstices, and resulted in a very complex time-keeping system of several interlocking cycles such as the Haab (365 days), the Tzolkin (260 days), and the Venus cycle (584 days). Their Long Count system recorded larger cycles of time, consisting of 13 cycles of 144.000 days each. 13. 0. 0. 0. 0. refers to the end date of the Long Count's last cycle -- which will be the winter solstice of December 21, 2012.
The Maya recorded their history and knowledge in books known as codices, most of which were burned in the 16th century as part of the process of conversion to Christianity. The three codices that survived were taken to Europe, where they are known today as the Dresden, Paris, and Madrid codices.              -  Carlos Delgado
