This article explores how the use of mobile phones has changed the contemporary Finnish soundscape. The change manifests itself firstly via telephone conversations which have spread from private premises to public places and secondly via interchangeable ringing tones. Drawing on research carried out among cellular phone users, the article argues that the ringing tones are selected on the basis of musical taste, so they can no longer be regarded as impersonal telephone signals. They can be used as a means of distinction and identity like any music. Even if the quality of ringing tones is inferior to the original interpretation of the tune, they can still be considered to be music, because of their personal and collective associations.
