-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 measures are the entropy rate, redundancy and \emph{predictive information rate}\cite{Abdallah:2009p4089} in the melody. Predictive information rate is an information measure developed as part of the Information Dynamics of Music project(IDyOM)\footnote{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 model and how it forms the basis of the Melody Triangle.  We outline two interfaces and uses of the system.  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 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.

+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.
