found: Edkvist, I. The performance of tradition : an ethnography of Hira Gasy popular theatre in Madagascar, 1997:p. 11 ("This study deals with the contemporary Hira Gasy performance in the regions of Imerina and northern Betsileo in the central highland of Madagascar. Hira means song and gasy is an abbreviation of Malagasy. Hira gasy, then means 'Malagasy song' in a broad sense. But it also designates a quite specific kind of performance called Hira Gasy ... The Hira Gasy performance is a kind of multi-media show using speech, song, dance, music and acrobatics.") p. 85 ("The four main parts of the Hira Gasy performance are the speech, the mother song, the young boys' dance, and the finale which consists of the child song and the folk dance.")
