Zoran Šćekić's ensemble "Nine Fragments for Alto Saxophone" (2014), performed by Antica Berislava and published on the CD album "Fragments," is the result of the first music-scientific research conducted as part of the ADRIA Microtonalis project, inspired by Gospin plač, a traditional chant from the island of Hvar, which is part of the Great Week ritual known as the Night Procession Za križem, protected by UNESCO. The name Procession Za križem comes from the collective name Processio Microtonalis as well as from its individual project ADRIA Microtonalis. The long-term collaboration between the composer and performer in this composition included fieldwork, the study of chants, analysis, and transcription of the sound recordings of Faroski kantaduri singers, designing systems of notation that capture the characteristic microinterval structures of the chants, and finding the best way to incorporate such musical material into the nature of the instrument and the composer's poetics. The transcription and intonational analysis of the sound recording of the traditional Gospin plač revealed that within the interval of a fifth, there are 13 different tones. Therefore, the odd-numbered fragments are based on the untempered 13-tone division of the fifth, while the even-numbered fragments are composed in the tempered system, centered on three short melodic themes created from two chants from Gospin plač.
