Launeddas is a Sardinian triple-clarinet. There are now nine types of Launeddas, each in a different mode. The main repertoire of launeddas is dance music. Its improvisatory performance is based on the compositional principle iskala, a series of pikkiada groups (an individual pikkiada consists of periods of six or nine measure) whose selection and order is aesthetically determined. Each of the nine types of launeddas has its own iskala.The existing studies have failed to differentiate between the theory of iskala and its performance practice. Through the course of fieldwork I hoped to develop a theory that would support iskala performance practice. From my fieldwork I have discovered that that the concept of iskala varies between regions, generationsand players, I decided to concentrate on the repertory of Aurelio Porcu (1915-), one of the oldest of the current generations of performers. Porcu's tradition derives from the Sarrabus, central region of launeddas playing. His repertory was inherited from his masters, some of the greatest launeddas performers. Porcu devoted his life career to a professional launeddas performance. As heir to one of the central launeddas traditions, analysis and understanding of his performance and repertory is vital.Through analyzing the structural characteristics of iskala, this thesis attempts to clarify the aesthetic process underlying iskala performance.Analysis revealed the following three points, as follows. First, the pikkiada groups that form the iskala, is are arranged according to the dance. Although the selection of pikkiada varies according to iskala, two pikkiada groups emerged as common to all iskala performance; furias and pass'appuntau, both of which are related to dance steps. It can consequently be said that the structure of iskala performance mirrors the structure of the dance ‹opening→furias→pass'appuntau→end›.Second, in performance, there appear two characteristic features of the iskala. The first of these is what I refer to as “flexible framework”. This refers to the length of performance. As launeddas players decide on the spur of the moment how to develop pikkiada groups, they can control the length of performance, making it as long or short as necessary.Furthermore, according to Porcu there is an aesthetic principle that no pikkiada group shall be repeated, what I refer to as a “one way principle”. This is a somewhat contradictory principle for launeddas players urged to play long performance. The existence of the “one way principle” demonstrates that launeddas dance music, based on a concept of the iskala, is a well-ordered logical construction.Third, there appears to be an ideal “pikkiada matrix” for each of the pikkiada groups. When Porcu teaches iskala, he demonstrates various sequences of pikkiada in each group (Porcu calls each pikkiada group merely “sa pikkiada”, i. e the pikkiada). These are regarded as examples of typical pikkiada, in which there is no fixed or privileged pikkiada like theme, contrary to the explanation in the former studies. In the performance launeddas players can freely decide and play various versions of pikkiada in each group providing they follows the proper pattern at each stage of the hierarchy (motif, phrase, and whole pikkiada of each group). While this is not a concrete pattern that players are bound to adhere to, it appears that this has been extracted as a successful model of performance by experienced launeddas players. As a result, performing launeddas dance music can be interpreted as cr
