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.
