Hát Xoan (Xoan singing) or cửa đình singing (singing at the village communal house) starts in spring during singing and dancing performances to worship the god in the village communal house. According to legend Hát Xoan appeared in the time of Kings Hùng, in the ancestral land of Hùng Vương—Phú Thọ, a province in the midland area of Vietnam. Gathering of Xoan singers who worship in spring called Xoan guild or families of Xoan. In a Xoan guild, there are between six and eighteen members. Men, called kép (instrumentalist), have to know how to beat a drum and sing the lead. Women are called đào (female singer). Female singers must not only be beautiful but also be able sing and dance well. The leader, called ông trùm, is an expert in art and master in all Xoan singing customs . He is also responsible for organizing and training instrumentalists and singers. Nowadays, in Phú Thọ province, there are four original Xoan guilds, in Kim Đới, Phù Đức, Thét, and An Thái villages. The Xoan guilds start their two-month spring itinerary 6 Jan (lunar calendar).\n\nXoan singing for worship is structured into three singing stages: Stage one is a ritual opening that includes songs such as Giáo trống, Giáo pháo, Thơ nhang, and Đóng đám. The Xoan guild of An Thái village opens with the song Chào vua while Xoan guild of Kim Đới village opens with Mời vua. Stage two is the performance of fourteen songs (known as quả cách) such as Kiều Giang cách, Nhàn ngâm cách, Tràng mai cách, Ngư tiều canh mục cách, Đối dẫy cách, Hồi liên cách, Tứ mùa cách, Quả cách is an ancient term. Quả means a long song while cách is a method of singing a specific song. Cách is the way ancient Confusion scholars expressed their feelings and conceptions of society and nature. The content of these fourteen songs is about wishing the four classes of people— scholars, farmers, craftsmen, and merchants—prosperity and fame. Stage three is a love-exchange song, including songs such as Bợm gái, Bỏ bộ, Xin hoa đố chữ, Gài hoa, Hát đúm, and Giã cá. The content reflects the desire of a couple’s love. Therefore, the items in this stage are usually performed by Xoan singers with local male villagers. The cultural exchange between Xoan guild and local male villagers make the singing session more attractive. However, Xoan singing was under the threat of being lost over time. On 24 November 2011, Xoan singing of Phú Thọ province was recognized as an Intangible Cultural Heritage In Need of Urgent Safeguarding of Humanity. In this CD, we selected and arranged some Xoan singing songs recorded and kept at Vietnamese Institute for Musicology in 1959.

CD7_CA HUẾ (THE HUẾ SINGING) IN CENTRAL VIETNAM\n\nCa Huế (the Huế singing) was a special traditional chamber music in Huế, a central city of Vietnam. Ca Huế originated from royal music. “There was the chamber music, serving the Nguyễn Kings and their mothers”. At first, Ca Huế was the chamber music performed in the palaces of royal families, mandarins, and wealthy people. After that, it spread to common communities. Ca Huế has been gradually influenced by many Huế folk musical types. During its development, Ca Huế affected royal music; for example, ten bản Tàu musical pieces (or it can be called ten bản Ngự or Thập thủ liên hoàn) were played in sacrifice ceremonies or some occasions in the court by royal instrumentalists. Ca Huế is the essence mixture of folk music and royal music, which creates the special nuance satisfying the artistic demand of the elite intellectual class and the common class. As a result, in the past, during happy occasions such as New Year ceremonies, parties for celebrating promotions, or parties for opening new businesses, Ca Huế was organised at the private houses of mandarins, the elite class, and Huế common people.\n\nIn the past, participants of Ca Huế included only the elite class, mandarins, and the people with erudite literary knowledge and with the ability to compose beautiful and profound lyrics. They played instruments together and shared their thoughts through instrumental music and singing. The singing and the instrumental music of one person was the inspiration for the singing and the musical composition of another. Group members were also the audiences. They enjoyed their mutual talents respectfully. In recent years, Ca Huế has been performed on stage to also serve the common people. In this musical type, there is a clear classification between composers, performers, and audiences like professional music. The interactive relation among group members of Ca Huế chamber music can be presently only found in Ca Huế in private houses.

The Central Highlands include five provinces: Gia Lai, Kon Tum, Đắc Lắc, Đắc Nông, and Lâm Đồng. This place is the residence of many ethnic minorities speaking two languages, Mon-Khmer and Malayo Polinesian. Ba na, Xê đăng, Mnông, and Xtiêng speak Mon-Khmer while Ê đê, Gia rai, and Raglai speak Malayo Polinesian. Local people in the Central Highlands have a very rich treasure of folk music. In religious festivals, music plays a significant role. The instruments such as gongs, after being played in festivals, are stored. They are considered sacred instruments and the properties that reflect the wealth of a family. In addition to religious music, folk music for daily life is equally as rich and includes music for love exchange, music played on fields, or music played in community houses. Indigenous people of the Central Highlands have innate musical talent. It is supposed that every person can become a singer and an instrumentalist. They are able to make instruments skillfully from bamboo, leaves, and stones, and they can perform music naturally, simply, and purely. The CD, called Folk music of some ethnic minorities in the Central Highlands, Vietnam, introduces some folk musical acts performed in daily life. These acts were recorded between 1977 and 1978 (track 1, 5, 11) and between 1997 and 1998 (the rest of tracks) and performed by local folk artists from ethnic minorities Ê đê, Gia rai, Xê đăng, Mnông, and Ba na in the Central Highlands.

CD6 CA TRÙ SINGING\nCa trù singing has other names such as hát ả đào, hát cửa đình, hát nhà tơ, hát nhà trò, or hát cô đầu. According to Đại Việt sử ký toàn thư (The Complete Book on the History of Đại Việt), Ca trù appeared in the Lý dynasty (1010-1025) under the name Ả đào singing. Many Ả đào singing contests were held in the village communal houses. In that time, village notables often played the praised drum while enjoying the performers singing and threw reward cards to the singers who performed well. That card was call “trù”. Gradually, the way of rewarding the singers with cards became known as Ca trù. This name is found in the poem namely “Nghĩ hộ tám giáp làm giải thưởng cho cô đào hát” (“On Behalf of People from Eight Hamlets to Write the Rewarding Rule for Awarded Singers”) of Lê Đức Mao in 1500. Ca trù is a popular genre of traditional singing and dancing of the Kinh people in the northern and the central Vietnam. The key members of a Ca trù band include one đàn đáy (three-stringed lute instrumentalist) (the đàn đáy is the only musical instrument for accompanying Ca trù), one singer who both sings and plays the phách clappers, and one praise drummer (known as quan viên cầm chầu) player.\n\nCa trù can be performed in a wide variety of places. Ca trù was born to serve as worship singing. From serving as worship at the village communal houses and ancestor worship, Ca trù has changed into singing for entertainment at private houses, restaurants, or cabarets. In addition to these main performance environments, Ca trù was performed at the royal palace and the palaces of mandarins. At present, Ca trù is sung as traditional music. In each performance environment, Ca trù has some changes in terms of the repertoire, musical nature, or performance styles. The CD Ca trù singing (Hát Ca trù) introduces some songs that which were performed for worship and for entertainment. They were recorded in 1970 (tracks 5, 6, and 7), in 1982 (tracks 1 and 4), and in 1997 (tracks 2 and 3) and performed by the three most famous Ca trù folk artists.

The northern mountainous regions are the residential land of the Kinh people and twenty-eight out of fifty-four ethnic minorities in Vietnam. This land has diverse forms of folk culture in general and folk music in particular. The CD, Folk Music of Some Ethnic Minorities in the Northern Mountainous Regions of Vietnam introduces some repertoires of folk music that were recorded in 1959 (tracks 1, 2, 5, and 7), in 1964 (tracks 10 and 15) and in 1970 (tracks 3, 4, 6, 8, 9, 11, 12, 13, 14, and 16) and performed by folk artists from minority ethnic groups, such as Thái, Tày, Nùng, Cao lan, Phù lá, Hmông, of the northern mountainous regions. Although the sound quality of the recordings isn’t that good, the materials will be valuable to history and art researchers and those who love folk music. The recordings allow listeners to compare folk art of a time that was almost isolated with the outside world with folk art of our time—the time of Internet.

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).

CD9_MUSIC OF TRADITIONAL THEATRE IN VIETNAM\n\nThe traditional theatre is an indispensable element in describing the appearance of traditional Vietnamese music. The forms of traditional Vietnamese theatre are mainly practiced by the Kinh ethnic group and some ethnic minorities such as Khơ me and Nùng. Two special forms of traditional theatre with long histories are Tuồng (classical drama) and Chèo (traditional operetta) of the Kinh group. These art forms gather many elements, including literature, painting, music, dance, and drama.Tuồng was born in northern Vietnam and performed in the court, and then followed mandarins to central and southern Vietnam with a new name Hát bội or Hát bộ. Tuồng was perfected and reached its peak in the Central Vietnam from the seventeenth century to the eighteenth century in the Nguyễn dynasty. Tuồng was performed not only in the court but also in common communities and was loved by common people. At the end of the nineteenth century and beginning of the twentieth century, Tuồng still played an important role in the spiritual life of Vietnamese people, especially to the people in central and southern Vietnam. Tuồng was one of a few traditional Vietnamese artistic types, loved by the court and common people.\n\nIn its flourishing period, the artists of Tuồng were categorized into two ranks, including Tuồng thầy artists (professinal artists who are knowlegeable and have exemplary performance style) and Tuồng rong artists (semiprofessional artists who lack of knowledge and have seasonal performances, mainly giving impromptu performances in tuồng cường. The system of Tuồng is clearly categorized according to the content such as Tuồng pho (Tuồng with many acts and performed on many nights), Tuồng đồ (Tuồng with content closer to daily life and based on folk stories), and Tuồng tân thời (Tuồng with the stories from new novels). Special Tuồng plays called Tuồng ngự were selected by the Minstry of Rites to be performed for for the king’s enjoyment.

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.

Vakalutuivoce is a traditional duet chant performed by men, usually from the fisherfolk clan in the maritime islands and coastal communities of the larger islands. The chants usually tell of the successful fishing expeditions of the fisherfolk clans. \nContents may vary but usually hinge upon fishing and the coastal environment. For communities located in the islands of the larger islands, these chants are called Vakavunigasau. \nThe Vakavunigasau is a functional chant associated with tugging logs. It is constantly chanted at the construction of a house and aims to help break the monotony, boredom, and heaviness of labor. It also inculcates a sense of solidarity and unity among workers and keeps the work proceeding at a methodical and companionable rate. The singing style of Vakalutuivoce is parallel to that of Vakavunigasau. For example, a melody is added as an accompaniment to another melody.
