MANILA, Philippines -- The singing of the Philippine National Anthem during flag ceremonies in schools will not be accompanied by canned music, Education Secretary Jesli Lapus said in a memorandum released this Friday.

The memorandum contains guidelines on the proper use of the Philippine flag in schools.

It emphasizes respect for the Philippine flag, which Lapus said was a symbol of the country’s sovereignty.

Lapus ordered teachers and administrators to refer to Republic Act 8491, which states the proper manner in displaying the Philippine flag, as well as the singing of the National Anthem.

Quoting the law, Lapus said the Philippine flag should not be used as drapery nor should it be used as uniform. It should not be used as part of an advertisement and must not be displayed in front of buildings occupied by non-Filipinos.

Likewise, tattered or faded flags should not be raised in any school, Lapus said.
