Folk songs, in general, can be lyrical and subjective. They, however, do not convey the psychological intricacies of the sophisticated elite. Nevertheless, they reveal the feelings and sentiments of the common people, their deprivation and struggles, anguish and bitterness, torments and anger in a simple and straightforward manner. The stanzaic form of a folk song is usually four to six lines. The first part moves in a refrain and the musical pattern of a folk song generally consists of verse repetition. This often maintains the pattern of tri-, tetra- and pentatonic scales.
