The desire to learn more about the Istrian tonal sequence, as something that is part of the tradition of the region where I grew up, and my love for performing music prompted me to choose the piano subject for my final thesis. The selected compositions combine various musical genres, and they are the ones that inspired me to research composers and their compositions written in the Istrian style. The preparation for the performance was very challenging. In the piece Istarski islamei by the composer Hrvoje Puškarić, I had the additional task of transcribing the notes from the manuscript in the Sibelius, as well as the redaction of the sheet music text in consultation with the musician himself. Puškarić worked with me on several occasions on the performance of the piece itself, which, in addition to the Istrian tonal sequence, also included oriental music. Istarski preludij by composer Bruno Krajcar is an energetic composition written in a clear ABCBA form. Krajcar's Istarski preludij is very energetic in the A and B parts, while the C part is much gentler and more contrasting, where elements of jazz music are expressed. The composer also advised me on the performance of the piece with, of course, the constant help of my mentor throughout the entire process, dr. art. Melita Lasek Satterwhite. The goal of this work is primarily aimed at young people who grow up in Istria and the Croatian littoral. My hope is that when they become better acquainted with the Istrian tonal sequence, as well as listening to the works of these two composers, they will enthusiastically talk about them and be proud of the culture of the region where they were born.
