This paper focuses on the singing activity of prelingually deaf children under four years of age who are using cochlear implants (CIs) and presents a strand of a larger study that aimed to observe, record and analyse the musical activity of seven profoundly deaf children using CIs in the UK, for a period of one calendar year. The singing activity of deaf children has been the focus of only a limited number of studies. This paper presents the singing behaviour of very young deaf children viewed as a holistic, communicative experience and part of their general music-making that develops in time and in the company of others. In this paper, I analyse one example from the data and discuss various parameters that are involved in song openings of deaf children: the presence of significant others, preference for song material, reproduction of the structural aspects of song, kinesthetic and emotional involvement in singing and re-enactment of song experiences in the children's own private spaces.
