Chimney is a music generation system that ‘allows the composer to control only the musical material of a piece, leaving its evolution to an algorithmic agent whose decisions are unpredictable.’ Chimney uses a GUI canvas to visualise the interaction between the human’s musical selection and the system’s generated music.
‘An algorithmic random walker unsystematically roams throughout the screen: as it encounters an object, the sound associated to that specific object starts playing with a sound level which is proportional to its distance to the walker. The human agent can only decide the objects to be placed on the canvas, their position, and their size. Under these conditions, the musician cannot organise a temporal structure, which is entirely controlled by the algorithmic agent.’
