The Ma-yawa wangga repertory was given to songmen by the Marri Ammu ancestral ghosts known as Ma-yawa. Before the late 1960s, it seems that this repertory was frequently performed at Wadeye, but nowadays Marri Ammu people join their Marri Tjavin neighbours in performing the Walakandha wangga repertory for ceremony. All but one of the Ma-yawa wangga songs were composed by the senior Marri Ammu lawman and artist Charlie Niwilhi Brinken (c. 1910–1993), but so far as we know, no recording was ever made of him singing. Maurice Tjakurl Ngulkur (Nyilco) (1940–2001), the Marri Ammu songman, inherited the repertory and added one of his own songs to it. Since his passing in 2001, the songs have rarely been performed. With its strong focus on the Dreamings (ngirrwat) and Dreaming sites (kigatiya) of the Marri Ammu people, the Ma-yawa wangga repertory holds a unique place within the corpus.
