A Viewpoint Approach to Symbolic Music Transformation
This paper presents a general approach to the transformation of symbolic music. The method is based on viewpoints, which enable the representation of musical surfaces by sequences of abstract features. Along the transformation process, some of these sequences are conserved while some others are variable and can be replaced by generated ones. The initial piece is therefore seen as a template which is instantiated at each transformation. The method is illustrated in the paper with the particular case of transformations occurring at the harmonic level. New chord sequences are generated by sampling from a statistical model in a particular style. The pitch of the notes constituting the template piece are then transformed according to the generated chord sequence.
