 As an artefact this installation is an exploratory prototype, and occupies an ambiguous role in terms of purpose; it is in a nebulous middle ground between instrument and art installation[, and could also form a framework for a kind of dance performance].  One thing is clear is that as a vehicle for communicating ideas related to the expectation, pattern and predictability in music it is very effective.   
 
 \subsection{The Screen Based Interface}
-[todo]
-[screen shot]
-On the screen is a triangle and a round token.
 
-With the mouse you can click and drag the red token and move it around the screen.
-When the red token is dragged into the triangle, the system will start generating a sequence of piano notes.  The pattern of notes depends on where in the triangle the token is

+The Melody Triangle can also be explored with a standard keyboard and mouse interface.  A triangle is drawn on the screen, screen space thus mapped to the statistical space of the Melody Triangle.   A number of round tokens, each representing a melody can be dragged in and around the triangle.  When a token is dragged into the triangle, the system will start generating the sequence of notes with statistical properties that correspond to its position in the triangle.  
 
+Additionally there are a number of keyboard controls.  These include controls for changing the overall tempo, for enabling and disabling individual voices, changing registers, going to off-beats and changing the speed of individual voices.  The system gives some feedback by way of colour changes to indicate when a token has locked on to a new melody, and contains a buffer zone for allowing tokens to be pushed right to the edges of the triangle without falling out.

 \section{Musical Preference and Information Dynamics Study}
 [TODO!]
+We carried out a preliminary study
+
+
 The study was divided in to 5 subtasks.  The axes of the triangle would be randomly rearanged prior for each participant. 
 
  this first task, which will last [4/3] minutes, we simply ask you to move the token where ever in the triangle you wish,.  This allowed the participant to get use to the environment get use to the interface and get a sense of how position of tokens changes a melody.
