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. \end{abstract} \keywords{Information dynamics, Markov chains, Collaborative performance, Aleatoric composition}
