 \begin{abstract}
 %The Melody Triangle is a Markov-chain based melody generator where the input - positions within a triangle - directly map to information theoretic measures of its output. 
 
-The Melody Triangle is an exploratory interface for the discovery of melodic content, where the input - positions within a triangle - directly map to information theoretic measures of the output.  The measures are the entropy rate, redundancy and \emph{predictive information rate}\cite{Abdallah:2009p4089} of the melody. Predictive information rate is an information measure, developed as part of the Information Dynamics of Music project\footnote{(IDyOM) http://www.idyom.org/}.  It characterises temporal structure and is a way of modelling expectation and surprise in the perception of music.

 We describe the information dynamics approach and how it forms the basis of the Melody Triangle.  We outline two incarnations of the Melody Triangle where it was used with a Markov-chain based melody generator.  The first is a multi-user installation where collaboration in a performative setting provides a playful yet informative way to explore expectation and surprise in music.  The second is a screen based interface where the Melody Triangle becomes a compositional tool for the generation of intricate musical textures using an abstract, high-level description of predictability. Finally we outline a pilot study where the screen-based interface was used under experimental conditions to determine how the three measures of predictive information rate, entropy and redundancy might relate to musical preference.
