Ca trù is a complex form of sung poetry found in the north of Viet Nam using lyrics written in traditional Vietnamese poetic forms. Ca trù groups comprise three performers: a female singer who uses breathing techniques and vibrato to create unique ornamented sounds, while playing the clappers or striking a wooden box, and two instrumentalists who produce the deep tone of a three-stringed lute and the strong sounds of a praise drum. Some Ca trù performances also include dance. The varied forms of Ca trù fulfill different social purposes, including worship singing, singing for entertainment, singing in royal palaces and competitive singing. Ca trù has fifty-six different musical forms or melodies, each of which is called thể cách. Folk artists transmit the music and poems that comprise Ca trù pieces by oral and technical transmission, formerly, within their family line, but now to any who wish to learn. Ongoing wars and insufficient awareness caused Ca trù to fall into disuse during the twentieth century. Although the artists have made great efforts to transmit the old repertoire to younger generations, Ca trù is still under threat of being lost due to the diminishing number and age of practitioners.

Shashmaqam (means the six Maqams (modes)) is a Central Asian musical genre (typical of Tajikistan and Uzbekistan) which firstly developed in Bukhara. Shashmaqom (in Farsi - "Six maqoms") is a leading musical-cyclic genre of musical heritage of Uzbek and Tajik people. It includes a cycle of complex and perfect instrumental as well as vocal compositions encompassing different types of melos, forms, usuls (rhythmic formulae) and performances. Shashmaqom is a cycle consisting of six maqoms, namely Buzruk, Rost, Navo, Dugoh, Segoh and Iroq. Each of these consists of two parts respectively, i.e. instrumental one (which is called "Mushkilot") and vocal one (which is called "Nasr"), representing more than 250 cycles of instrumental and vocal compositions in total. Shashmaqom got formed in urban environment, and its bearers of traditions were well-known musicians and singers. Its vocal part was performed in Uzbek and Tajik languages. The texts were mainly taken from the poems of classics of oriental poetry (i.e. Rudaki, Jami, Lutfi, Navoi, Babur, Khafiz, Fizuli, Amiri, Nodira, Zebuniso, Ogahiy and others) and were dedicated to love-related, lyrical, philosophical, didactic, religious themes. Folk poetry examples were also used. Most widely used musical instrument was tanbur. It is based on tuning tanbur that the tonal basis of maqoms emerged. Instrumental part of each maqom included instrumental compositions such as "Tasnif", "Tarje", "Gardun", "Mukhammas" and "Sakil", performed either solo or by instrumental ensemble. However, each part differed with its own tune, character of melody, structure and usuls of doira. Vocal parts are considered the most difficult and complete ones in terms of structure, melos and form and are divided into two cycles (shuba): the first one includes "Sarakhbor", "Talqin", "Nasr" and "Ufar", performed by leading singer - hofiz (their melodies are more developed, of great range and complex form). Between main parts "Tarona" was sung by vocal ensemble as a connecting one (it is a small vocal piece, which has its own tunes, feature and forms). The second cycle (shuba) includes five-part cycles "Moghulcha" and "Savt" (except maqom "Iroq"). In addition to main parts, each maqom incorporates additional compositions: instrumental one (naghma, peshrav, samoyi, hafif), and vocal one (uzzol, ushshoq, bayot, chorgoh, nasrullo, oraz, khusayniy, navrozi sabo, khoro and ajam), the creators of which were bastakors (creators of oral musical tradition). Shashmaqom got formed, has been preserved, mastered and transmitted from generation to generation verbally, based on "Ustoz-shogird" ("master-apprentice") method of learning.

Katta ashula is a vocal direction, a song genre typical for the Ferghana Valley, in which peculiar style and manner of singing is observed. It is performed by two or more singers in turns and without accompaniment of musical instruments. Katta Ashula is characterized by laconism (in means of expression), expressiveness (in music language), dynamism (in melodic development) and bright emotionality. Its figurative structure (or style) is closely connected to the traditional (classical) poetry of lyrical and philosophical nature. And ghazals of Navoi, Lutfi, Mashrab, Khazini, Muqimi, Furqat, Zavqi, Miskin serve as main poetic texts in this genre. Though, since the XX century the poems of contemporary Uzbek poets (such as Sobir Abdulla, Charkhi, Chusti, Akmal Polat, Khabibi, and others) as well as examples of folk poetry have been widely used. In terms of subject matter katta ashula songs can be divided into love-lyrical, didactic, religious and contemporary ones. The origins of katta ashula genre should be looked for in ancient folk-ritual chants, songs of "praise" (such as marsiya, navkha, ayolgu), agriculture- and labor-related songs with their original combination of recitative-declamatory beginning and chanting; and in distiches of ghazals (ghazalkhonlik), written in aruz prosody. Performance with high-pitched voice, existence of culmination parts, clarity of words for and their impact to the listeners – all these are features of this type of song. Katta ashula has several genres, such as “Yovvoi maqom” (“Yovvoi Ushshoq”, “Yovvoi Chorgoh”),"Yovvoyi asula" ("Yovvoyi Tanovar", "Yovvoyi Munojat"), "Yakkahonlik" ("Ohkim, gulzorim qani topmadim").\nNotably, the emergence and development of Katta ashula genre is closely linked with existence of corresponding performance schools, which stand out with their style of interpretation, manner of singing and bearers. From among katta ashula performance schools it is possible to mention Qoqand, Margilan, Andijan, Namangan and Tashkent performance schools.
