CD5 HÁT VĂN\nHát văn (văn singing) is a special traditional music associated with the Tứ Phủ religion, a local religion of the Kinh people in Vietnam. Hát văn or chầu văn means singing for reporting something to gods. In religion, it can be called cầm ca chúc thánh, which means “singing for praising gods”. There is a sentence in a book: “The Buddha loves the scripture and gods love singing”. The combination between singing and instrument playing, various repertoire and melodies, and strict regulations in performing ritual music helped hát văn become a professional traditional music, which strongly attracts listeners. The Tứ Phủ belief (the Four-God belief) is the environment in which hát văn has been nurtured and developed. The Tứ Phủ belief mentions the gods of the four components of cosmos, the world located in Heaven, Earth, Water, and Mountains. These gods are ranked differently. At the top of the temple is the Father of the Jade Emperor. Under the position of that god are Tam tòa Thánh Mẫu, ngũ vị vương Quan, tứ vị Chầu bà, ngũ vị Hoàng tử, Tứ Phủ thánh Cô, Tứ Phủ thánh Cậu, Ngũ Hổ, and ông Lốt. The Mẫu Liễu Hạnh God is considered to play the center role. Before becoming one of four Vietnamese gods, he was a normal person on the Earth with the hometown and the name.\n\nThe people in charge of performing music in the Tứ Phủ belief are called cung văn. A person practicing the cung văn profession has to train for a long time, from five years to seven years. This person has to be excellent in writing Hán-Nôm words and organizing a worship ceremony and hát văn so that he/she can take care of a temple. The cung văn profession is transferred only to family members. Hát văn music is usually performed by two cung văn, including one person playing the nguyệt (moon-shaped lute) and the other playing percussion instruments. One of them or both can sing. In a big rite, the number of performers in a band can be four or five with the participation of the tranh (16-chord zither), the nhị (Vietnamese two-string fiddle), or flutes. The nguyệt originates from the yeuqin instrument of China. However, comparing to the yeuqin instrument, the nguyệt has a longer neck with eight to eleven frets. A neck with ten frets is the most popular. Two strings of this instrument used to be made of silk but now are made of nylon. The small string is called dây tiếu, and the bigger one is called dây đài. The nguyệt is usually tuned to dây bằng (the fifth interval) and dây lệch (the fourth interval). It is seldom tuned to dây tố lan (the minor seventh interval) and to dây song thanh (an octave).

CD4 QUAN HỌ BẮC NINH IN THE NORTH VIETNAM\nQuan họ,a special alternate singing between men and women, was once only available in Kinh Bắc region in northern Vietnam. Traditional Quan họ was previously the folk art of forty-nine villages in Kinh Bắc, which is presently Bắc Ninh and Bắc Giang provinces.Quan họ singing has been associated with twining occasions in the past. Quan họ is often sung between two groups, called bọn Quan họ, who are living in two different villages and wanting to strike up friendship with each other. During annual festivals or their free time, the Quan họ people sing to satisfy their demand for exchanging art. They sing throughout the day and night. The twining relationship between the Quan họ performers as artistic and intimate friends has continued from forefathers to descendants; thus, they are never allowed to marry each other. Quan họ is one of the few musical forms that has alternate singing between men and women and lyrical love-exchange lyrics but has no the function of love-exchange in daily life as other love-exchange folksongs.\n\nNevertheless, Quan họ is sung not only by twinning Quan họ people but also by others from other places. People can sing Quan họ at many locations; for example, they can perform it at houses at night on normal days, at temples on festivals, on hills, in the forest, along the street, at ponds, or on boat.In Quan họ singing, the male group is called liền anh, and the female group is called liền chị. Traditional Quan họ is pair singing without accompaniment. One of the pair is in charge of singing, leading the tune while the other sings as a secondary part. These two people have to be selected and trained to be in perfect harmony at the same timbre. In addition to pair singing, there is group singing, which is performed on congratulatoory and worshipping occasions. The male group sings in response to the female one. Four typical singing techniques of Quan họ are resonant, ringing, restrained, and staccato.

CD8_ĐỜN CA TÀI TỬ, A CHAMBER MUSIC OF SOUTHERN VIETNAM\n\nĐờn ca tài tử is a special traditional genre of chamber music of the Việt people in southern Vietnam. In comparison with other forms of traditional musical performances in Vietnam like Ca trù (Ca trù singing), Ca Huế (Hue singing), etc, the art of Đờn ca tài tử was a late traditional form. According to many musical researchers, Đờn ca tài tử came into being in the mid-nineteenth century from the musical context of the ceremonial music nhạc Lễ of southern Vietnam and the chamber music nhạc Huế. Historically, nhạc Lễ played a very important role in the cultural life of southern Vietnam. The repertoire was divided into two styles played by a martial ensemble phe võ and a classical ensemble phe văn. The phe võ is composed of drums, cymbals, and the Vietnamese oboe kèn bầu. The phe văn consisted of stringed instruments, particularly four types of the cò (two-stringed fiddles, such as the cò, the cò chỉ, the cò tre, and the gáo fiddle), and percussion instruments such as the trống nhạc (drum), and a trống cơm (a small cylindrical drum).\n\nThe two ensembles are invited to play at major village festivals. But for less important occasions such as weddings, birthdays, and housewarmings, a smaller phe văn group is called in, which includes the stringed instruments without percussion instruments. This ensemble is called đờn cây. For the need of artistic entertainment, other stringed instruments progressively joined this ensemble such as the đàn tranh (sixteen-string zither), the kìm (moon-shaped lute) and the very small wooden song lang. Music gradually escapes the solemn nature of rituals to serve daily life. It can be considered the initial foundation of Đờn ca tài tử, but it was not yet the Đờn ca tài tử. In 1885, when the Huế capital fell, the immigration of instrumentalists of the Nguyễn court from central Vietnam to the southern region made significant influence on the development of Đờn ca tài tử. At this time, Đờn ca tài tử was actually shaped after acquiring Huế chamber music in both repertoires and performance styles. The emergence of Đờn ca tài tử has received great support and favor of the majority of people in the southern Vietnam.
