This paper explores the relationships between sound and its visualisation, focussing upon the issues surrounding representation and interpretation of music through both performative and machine processes. The discussion proceeds in the context of five recent works by the author exploring the representation of sound and musical notation and their relationship to and with performance: unhörbares wird hörbar (the inaudible becomes audible) , EVP , Lyrebird: environment player , Nature Forms I  and sacrificial zones . Issues examined include: re-sonification of spectrograms, visualisation of spectral analysis data, control of spatialisation and audio processing using spectral analysis data, and reading issues related to scrolling screen score notation.
