The Academy of Music and Theatre ("Hochschule für Musik und Theater") offers graduate degrees in artistic fields. Founded in 1994, the institution combined "Ernst Busch", the former drama school, and the outpost school of the Hanns Eisler Music School Berlin. Today, the combined school is a member of the Association of Baltic Academies of Music (ABAM), a union of 17 music conservatories at the Baltic Sea and Israel. Unique in Europe is the postgraduate degree in piano duo performance. The school possesses a large opera stage (Katharinensaal) and two chamber music halls. There are concerts every day throughout the year.
