If a visitor came to the Philippines, I'd want them to hear a folk song called Bahay Kubo. It's very simple, and almost every Filipino child learns it, but I think it says a lot about us.
The title means a little nipa hut, which is a traditional house made of bamboo and palm leaves, raised on stilts. The song describes the hut, and then lists all the vegetables growing in the garden around it, things like radish, eggplant, beans, ginger, garlic and squash. It has a cheerful, easy melody, so even people who don't speak Tagalog can hum along after hearing it twice. I first learned it in kindergarten in Iloilo, and we'd sing it in a circle, pointing to pictures of vegetables. You still hear it at school concerts, family parties and even in some restaurants that serve traditional food.
I'd want visitors to hear it for several reasons. Firstly, it shows our connection to the land. My grandparents were farmers, and the idea of a small house surrounded by food you've grown yourself represents a kind of simple, self-sufficient life that many Filipinos still feel nostalgic about, even if we now live in cities. I'm a nurse in Manila, and my apartment certainly doesn't have a garden! Secondly, it reflects how musical Filipinos are. We sing at every opportunity, and teaching a visitor a song is a friendly way to welcome them. And finally, it's fun. When I worked abroad in Dubai for two years, I taught it to colleagues from Kenya and Lebanon, and it became our silly lunchtime song. That showed me how a little folk song can travel.
