A musical art with both scholarly and folk roots, ??n ca t�i t? is an indispensable part of the spiritual activity and cultural heritage of the people of southern Viet Nam. The music and songs evoke the people�s life and work on the land and rivers of the Mekong Delta region. Performed at numerous events such as festivals, death anniversary rituals and celebrations, ??n ca t�i t? is thus intimately connected with other cultural practices and customs, oral traditions and handicrafts. The performers express their feelings by improvising, ornamenting and varying the �skeletal melody� and main rhythmic patterns of these pieces. ??n ca t�i t? is played on a variety of different instruments, including the moon-shaped lute, two-stringed fiddle, sixteen-stringed zither, pear-shaped lute, percussion, monochord and bamboo flute. Its repertoire is based on twenty principal songs and seventy-two classical songs.
