-The Melody Triangle is a musical pattern generating system.  It has two interfaces; one is a traditional screen based interface, the other a multi-user interactive installation.  In both cases, the Melody Triangle allows its users to interactively explore patterns of predictability in music. It makes use of statistical models developed as part of Information Dynamics of Music(IDyOM) project[ref], which seeks to model patterns of expectation and surprise in the perception of music.   
+The Melody Triangle is a Markov-chain based musical pattern generator who's input parameters correspond to information theoretic measures of the system's own output.  The primary user input, positions within a triangle, directly maps to the amount of entropy, redundancy and \emph{predictive information rate}\cite{Abdallah} of output melodies. Predictive information rate is a \emph{time-varying} information measure.  Developed as part of the Information Dynamics of Music project(IDyOM)\footnote{http://www.idyom.org/}, it is a way to characterise temporal structure, modelling expectation and surprise in the perception of music.
 
-We outline the Information Dynamics model and how it forms the basis of the Melody Triangle.  We discuss both uses of the system, the multi-user installation where collaboration in a performative setting provides a playful yet informative way to explore expectation and surprise in music, and the screen based interface where the Melody Triangle becomes compositional tool.  Finally we outline a study where participants used the screen-based interface under various experimental conditions to allow us to determine the relationship between the Information Dynamics models and musical preference. We found that\dots

We outline the interfaces to the system - a multi-user installation where collaboration in a performative setting provides a playful yet informative way to explore expectation and surprise in music, and a screen based interface where the Melody Triangle becomes compositional tool that allows for the generation of intricate musical textures using an abstract, high-level description of predictability. Finally we outline a study where participants used the screen-based interface under various experimental conditions to allow us to determine the relationship between the Information Dynamics models and musical preference.

 \section{Introduction}
 
- Music generally patterns in time. Composers commonly, consciously or not, play with his or her audience's expectations by setting up patterns that seem more or less predictable, and thus manipulate expectations and surprise in the listener[ref].  The research into Information Dynamics explores several different kinds of predictability in musical patterns, how human listeners might perceive these, and how they shape or affect the listening experience.
+ Music involve patterns in time, and when listening to music we create expectations of what is to come next, and composers commonly, consciously or not, play with this expectation by setting up expectations which may, or may not be fulfilled, and thus manipulate expectations and surprise in the listener[ref].  The research into Information Dynamics explores several different kinds of predictability in musical patterns, how human listeners might perceive these, and how they shape or affect the listening experience.
