The longstanding tradition of cross-genre musical creation in the Philippines underpins the many works that fall into the broad, intentional category of Music/Mix, a classification built to hold sounds that resist narrow, single-genre framing. Genre classification as a tool for cataloguing recorded sound has long struggled to keep up with the dynamic, evolving nature of musical creation, particularly in regions like the Philippines where cross-pollination between different sonic forms is a core part of creative practice, rather than an exception. Long before formal genre labels existed to categorize recorded sound, creators across the Philippine archipelago were weaving together distinct regional sonic practices, liturgical musical forms that emerged through centuries of cultural exchange, and popular global sounds that traveled through trade, migration, and mass media to create works that defied simple categorization.
