The Baroque Orchestra on Historical Instruments (BaHI) focuses on the interpretation of music between the early Baroque and Classical periods and is mainly composed of students from the "Historical Instruments" department who specialize in this field, but also interested students from the "modern" instrumental subjects. It rehearses weekly in different instrumentations under the guidance of various lecturers of the department and plays, among other things, at the festival "Early Music Days", in selected concert and oratorio events and the annual baroque opera productions of the Opera School.
