This paper discusses the aspects of flexibility and integration in the performance of samba batucada, a Brazilian collective percussive practice. Departing from the sonic visualization of two examples – Bateria de Bamba and Bateria Alcalina – I present some perspectives of the samba's rhythmic structure and the relation between sound patterns and body movements. Flexibility and integration may be seen as inherent aspects of the collective music making, reflecting some further issues of the ">batucada experience.
