Abstract：This article introduces Sara Adhitya's design practice and theoretical research on music and the city, reviewing her
study on "Musical Cities" from 3 aspects: Sonified Urban Masterplan, Composing the City, and Urban Sonic Interaction
Design. Her research on "Musical Cities" in the context of her practical experience in Paris, Perth, and London is discussed,
which process consists of "listening", understanding and representation of the urban environment; "composing",
musical urban planning and design; and "performing", implementation and experience of the city.
