Music technologies are becoming important in children's play in everyday life, but research on children's communication and interaction in such activities is still scarce. This study examines three children's social interaction in an 'experimental' activity in preschool, when the music technology breaks down. Detailed analysis is carried out by using a Goffmanian approach. The findings illustrate the children's interpretive framings of the adult's introduction and their orientation to the technological material in order to perform different alignments and how they change footings. The children's social interaction is organised according to the playful framing of the bracketed activity. This suggests the significance to pay attention to children's definitions of situations and to consider children's experiences of participation in popular media culture.
