The Yami tribe on the isolated Orchid Island is a community of about 2,000 people organized around fishing teams, and impress you with their palm fiber cloths, silver pieces hats, beautifully carved colorful boats, and complete nudity ( except occasional T-shaped loincloth ). This tribe has been isolated from other cultures for long time till recently, and still staying in a very primitive stage. From the points of musicology, their songs offer interesting data on the origin of music.
    The songs of the Yami has not evolved from the most simple, primitive, and natural expressions.
(1) Almost all the singings are Homophonic and recitative.
(2) Most of the songs have lyrics, but some of the working songs repeat fixed beats with nominating sounds.
(3) The contents of their songs are closely related with their daily life: fishing, boat building, house building, ancestors, ghosts, and evils, etc.
(4) The tonal system is the most primitive, and has only two kinds:
    a) two or three tones of the second or the third.
    b) alternative use of a central tone and an ascending or descending fourth.
    The former is for the recitative, and the latter is for working songs, with rhythmical shoutings accompanying their actions.

    This is the least culturally developed tribe with a very peculiar tonal structure. The most fundamental scale consists of do, mi, and mi^(b), in the Enge-melodie type. About 60 to 70% of their songs are sung in this scale, most being fishing and farming songs. But the contents of their songs are interesting and various.
