Ateneo's cheering tradition consists of cheers, yells and songs that imbibed the Ateneo spirit. They added much to the clapping of hands and stomping of feet by inspiring and willing the school varsity teams to victory time and again. There are no records of when and who wrote the Ateneo's cheers and yells. The cheers are said to have been inspired by Roman traditions. Contrary to popular belief, the cheers themselves have no literal meaning such as Fabilioh and Halikinu, which some mistake for Greek or Latin words. They are just letters put together and have a rhythmic sound. The yells of Ateneo are one to three words of encouragement such as "Fight", "Animo Ateneo" and "Get that ball". The Ateneo songs are the opposite of the cheers. They are all intelligible and the composers of some of them are known. After the eagle was officially chosen as the school's mascot, the fight song, "Blue Eagle – The King" was composed by Raul Manglapus (AB '39) in the summer of 1939. The marching song, "Cheer, cheer and Go!" was composed by Lamberto Avellana (AB '37). Some songs like "Hail! Ateneo Hail!" and the Ateneo Cadet Corps March were adopted and modified from cheer songs of American Jesuit schools, such as Fordham. The music were borrowed and new lyrics were written or the proper names were just changed. A cheerbook, titled "On Wings Of Blue" was published in the 1930s and reprinted in the 1950s and 1987. This first edition contains all the songs, cheers and notes compiled from since the cheering tradition began before the foundation of the NCAA. This small blue booklet featured as well, interesting tidbits about things Atenean such as the colors, shield, motto and the mascot of the school. The 1998 edition has gone through some revisions, including the addition of the "Song for Mary".
