In this paper, the research on Istrian-coastal music continued on the basis of the author's final work "Istrian folklore elements in the piano works of Đeni Dekleva-Radaković". The works of contemporary Istrian composers Đeni Dekleva-Radaković are presented, and for the needs of the work, biographical data were collected and three representative four-handed piano compositions were analyzed. In his four-handed works, Dekleva-Radaković uses modern composition techniques and combines them with traditional elements. It is a combination of tonality and atonality, the use of aleatorics, but also traditional elements. A piano opus is also cited in which the composer is also likely to use the cited elements. With such a combination, Đeni Dekleva-Radaković arouses the interest of the listeners, and the desire of the performers for a deeper understanding of the Istrian way of composing and Istrian music in general. The first part of the paper describes the Istrian-coastal tone sequence. It is presented through theoretical setting, definition and harmonization. Emphasis is placed on its development from folklore beginnings up to the use of scale in artistic literature. The prominent elements of the mentioned scale are followed by a biography of the contemporary Istrian composer Đeni Dekleva-Radaković who skillfully interweaves the Istrian scale with contemporary composing techniques. The combination of tradition and modern techniques is evident in the compositions for four-handed piano („Šegun-Šegač“, „Danze capricciose“ and „Tri slike“) in which the Istrian scale plays a large role. The aim of this paper is to bring Istrian-coastal folklore music closer to those interested, to emphasize its importance and to encourage its use in artistic literature. Knowledge of the Istrian-coastal sound sequence and Istrian music is limited in the Croatian area, and the aim of this paper was to broaden the horizons and bring closer the content of those interested.
