Passage: A wide variety of oral and written literature has developed in Madagascar. One of the island's foremost artistic traditions is its oratory, as expressed in the forms of hainteny (poetry), kabary (public discourse) and ohabolana (proverbs).  An epic poem exemplifying these traditions, the Ibonia, has been handed down over the centuries in several different forms across the island, and offers insight into the diverse mythologies and beliefs of traditional Malagasy communities. This tradition was continued in the 20th century by such artists as Jean-Joseph Rabearivelo, who is considered Africa's first modern poet, and Elie Rajaonarison, an exemplar of the new wave of Malagasy poetry. Madagascar has also developed a rich musical heritage, embodied in dozens of regional musical genres such as the coastal salegy or highland hiragasy that enliven village gatherings, local dance floors and national airwaves. Madagascar also has a growing culture of classical music fostered through youth academies, organizations and orchestras that promote youth involvement in classical music.
