In this paper, we consider musical ringtones of mobile phones to act as virtual, communicative and cultural performances. They appear unpredictably, they communicate signs which are interpreted by a variegated and dynamic audience, and establish stages upon which cultural meanings are portrayed. We will argue that the musical ringtone functions as a musical madeleine in Marcel Proust's sense, an involuntary mnemonic trigger of a complex web of individual and collective memories. Having this quality, the ringtone lends itself perfectly to the performative manifestation and display of (sub)cultural identities in the public sphere.
