Oru Seco is the Bata drum cycle, without songs. Adrian Coburgs transcription book of Afro-Cuban Bata scores contains basic Bata rhythm patterns and additional solo parts. These are principal Bata scores to be played as the opening of religious ceremonies. The Bata rhythms are presented in a definite order to call the Orishas. Adrian Coburgs collection opens with Elegua and ends with Oddua, which is the order traditionally played at ceremonies in Havana. It is preserved and transmitted in oral heritage by Santero Julio Davalos (Awó Chadeé) to Adrian Coburg (Otruponka, Omo aña ewue Osain).
