The Flag Act of 1907 prohibited the use of the anthem and other Philippine revolutionary and Katipunan symbols for a short period of time. When it was repealed back in 1919, the Insular Government decided to translate the hymn from its original Spanish version to the English version. The first translation was written around that time by the renowned poet Paz Márquez Benítez of the University of the Philippines. The most popular translation, called the "Philippine Hymn", was written by Senator Camilo Osías and an American, Mary A. Lane. In the 1920s, the time signature in performance was changed from 2/4 to 4/4 to facilitate its singing and the key was changed from the original C major to G. However, this change was not codified into law. The anthem was played alongside the United States anthem, "The Star-Spangled Banner", which was adopted in 1931. It was played alongside each other until the country's eventual independence in 1946.
