The kundiman is a Philippine traditional song form which expresses feelings of romantic love or intense longing and devotion. The name is probably derived from the phrase “kung hindi man” (“if it should not be so”), which was used in the early examples of this type of song.
While a folk song is one that uses traditional melodies and/or modes to speak on a particular topic. Often, topical folk songs address social and political issues such as work, war, and popular opinion; although not all folk songs are topical or political. Some are personal dirges or ballads about family stories, love songs, or even nonsense songs.
