"Trance means an altered state of mind in which a person becomes capable of communicating with spirits by the means of a ritual. Echo like sounds have a significant role in the piece, they were achieved by aleatoric as well as metric materials. Our prehistoric ancestors experienced echo as a side effect of rituals they performed, basically they heard the echo of their own voices but they believed these sounds came from their ancestors. As 2013 was the 90th anniversary of György Ligeti's birth, my piece pays respect to his musical heritage. In this regard the piece references Ligeti's artistic aesthetics and in some cases uses direct musical quotations."(Máté Bella, 2013)The work won first prize at the 2013 New Hungarian Music Forum In memoriam György Ligeti composer's competition in chamber music category.
