 The sonata was written during Zivkovic’s studies at the Music Academy in Belgrade, in the class of Vlastimir Trajković.The emotion and expression of the music is extremely unusual and original, because it doesn't allude in any way to human emotion, or anything formed by the nature.Sighs, sound phrases, wide vibrato, glissandos... everything in this music is in a function of some unusual fascination, spiritual and intuitive onomatopoeias and brave identification of the world of angels.
