  Smart cities are urban areas with sensor networks that collect data used
towards efficient management. As a source of ubiquitous data, smart city
initiatives present opportunities to enhance inhabitants' urban awareness.
However, making sense of smart city data is challenging and there is a gap
between available data and end-user applications. Sonification emerges as a
promising method for the interpretation of smart city data and the production
of novel musical experiences. In this paper, we first present the smart city
paradigm. We then cover the topics of ubiquitous and mobile music, followed by
an overview of sonification research. Finally, we propose an approach entitled
ubiquitous sonification and present the initial design of a speculative use
case for musical smart city systems, leveraging user and urban data to inform
behaviour.
