Answer:
Mindanao- Mindanao also has the largest concentration of ethnic minorities in the Philippines. They include the Magindanao, Maranao, Ilanun, and Sangil; all are Muslim groups sometimes collectively called the Moro. Groups usually found in the uplands include the T'boli, Subanon, Bukidnon, Bagobo, Mandaya, and Manobo.
Mindanao music influences- Mindanao folk music includes the ancient Muslim folk song and dance called estijaro, and a Mindanao folk song called uruyan. These are usually accompanied by drums, gongs, or other percussion instruments like the subing, a gong.
Mindanao beliefs- Roman Catholic and Islam are the two religions most widely spread across Mindanao. These two denominations together cover the religious affiliation of more than half of the islands' population.
Mindanao tribes- The Lumad tribal groupings of Mindanao include Ata, Bagobo, Guiangga, Mamanwa, Magguangan, Mandaya, Banwa-on, Bukidnon, Dulangan, Kalagan, Kulaman, Manobo, Subanon, Tagabili, Takakaolo, Talandig, and Tiruray or Teduray.
Mindanao culture- Mindanao is a Muslim outpost in the predominantly Roman Catholic Philippines. Although Muslims are no longer a majority, Islamic culture is evident; there are many mosques, and distinctive brassware, including the kris, or dagger, is manufactured.
