thanks for the comment. it is avan-garde because it's not any traditional piano music form, some keys are played out of their normal positions, it has no line of development,it rather gets killed slowly and violently, and it's rather fragmentary in its static movement (vertical) and etc.
(maybe it's not so avant-garde as postmodern in its stylistics, though, as i have mentioned - my friend referred to it as very cold and two times said - avantgarde avantgarde, so i took it for granted
