This dissertation is a guide for learning extended violin techniques that have not been extensively regarded in academic studies until now. The profound changes and additions to the sound palette of the violin in the twentieth century (often with techniques that oppose a classical approach to the instrument) has made necessary the study and compilation of the contemporary techniques not taught by traditional methods. However, even though studies and methods on extended techniques already exist, there are considerable gaps and weaknesses in them. Thus, the present text has been developed as a step towards compensating for a few of the gaps, such as: the limitation to European and North American concert music repertoire; the lack of pedagogical approach; and the lack of audiovisual resources. As a result, this study brings detailed overview with didactic comment, practice exercises, and video demonstrations of techniques found in Argentine tango, Brazilian concert music, North American folk music, and Salvatore Sciarrinos caprices. A set of experimental caprices has also been developed to explore those techniques mixed with other extended techniques more common in the repertoire. Although primarily conceived as a guide for violin performance and teaching, the text has been designed to be a useful resource for composers, conductors, and researchers interested in extended techniques.
