+\title{Information Dynamics Installation\\Pattern and Predictability in Music}
+\author{Samer Abdallah and Henrik Ekeus}
+\begin{document}
+\maketitle
+One of the noticable features of most sorts of music is that it
+involves patterns in time---a repeating bass line, the cycle of
+harmonies in a 12 bar blues, a melodic theme that is repeated, perhaps
+in slightly different forms, at different pitches or at different speeds, and so on.
+One of the tools available to a composer or performer is to play
+with his or her audience's expectations, by setting up patterns that
+seem more or less predictable, sometimes doing what listeners expect,
+and sometimes doing surprising things.
+
+Our work on \emph{information dynamics} involves studying several
+different kinds of predictability in musical patterns, how we as
+human listeners might perceive these, and how they shape or affect
+the listening experience.
+
+This installation allows participants to explore a space of melodic
+and rhythmical patterns organised by \emph{how predictable} they are,
+at least according to a simple model of how one might guess the next
+musical event given the previous one.
+Each person in the space generates one instrumental line, at a certain speed
+and using a certain pitch range. 
+
+\subsection*{Moving around}
+As you enter the space, the system will start generating an instrumental
+line or voice.  The loudness of your voice is linked to your height,
+so if you crouch, you will become quiet. The active space is triangular,
+with each corner corresponding to three different extremes of predictability/unpredictability.
+As you move around, the system will generate patterns corresponding to
+where you are in the space. With other people in the space, you can 
+cooperate to create polyhonic textures, for example, you could lay down
+a predictable repeating ostinato or bass line while your companion can
+generate a freer melodic line on the off-beats.

+\textbf{Tip}\quad It's best not to move around too quickly, to give yourself
+time hear the pattern you are generating to notice its characteristics.
+Then you can decided if you like it or want to try somewhere else.
+If you move around quicky, the patterns will change so quickly that there
+will effectively \emph{be no pattern}.

+\subsection*{Control gestures}
+\def\out{in$\rightarrow$ out}
+\def\in{out$\rightarrow$ in}
+Control gestures are made pushing out or pulling in your left and right
+arms rapidly, either separately or together (while facing the Kinect
+motion tracker; if you face away, then left and right are reversed).
+
+It should be noted that the system will sometimes detect gestures when
+none was intended. In particular, you might find the timing of your voice
+goes wild if you walk around quickly. In this case, the \textbf{(\in,\in)}
+gesture will reset your voice to the initial tempo and on the beat.
