Declaring Last Week of July as Philippine Music Week

Executive Order No. 255 (1987) mandates radio stations with musical programs to broadcast at least four original Filipino musical compositions every clock hour.
Definition of Original Filipino Music (OPM): compositions created by Filipinos, regardless of language or dialect.
Proclamation No. 1173 (1973) declared the last week of November as National Music Week for Young Artists.

Increasing public awareness and appreciation of homegrown music is critical for the revival of OPM.
Local music industry promotion contributes to:
- Advancement of Filipino art and culture.
- Economic development through employment and revenue generation.
- Support of other local industries.

The last week of July of every year is declared as Linggo ng Musikang Pilipino (Week of Filipino Music).
This is aimed to revitalize government efforts to promote Philippine music.

The National Commission for Culture and the Arts (NCCA) is designated as the lead agency to oversee the successful annual celebration nationwide.
All government departments, agencies, instrumentalities, government-owned and controlled corporations, local government units, and the private sector are encouraged to support and participate actively.
Radio stations with musical formats are encouraged to broadcast at least four OPM compositions every clock hour during the week.

All other public and private institutions are invited to play Original Filipino Music in their premises, where appropriate, to support the celebration.

The proclamation was signed on December 19, 2014, by the President of the Philippines.
It carries the seal of the Republic of the Philippines and urges collective participation for the promotion of Filipino music culture.
