After he left school he first went on to study composition and conducting with Cesar Bresgen and Gerhard Wimberger at the Mozarteum University in addition to musicology at the University of Salzburg with Professor Croll.
There then followed two years at the Conservatoire National et Supérieur in Paris studying under Olivier Messiaen and Pierre Schaeffer as well as following courses taught by Karlheinz Stockhausen and Luciano Berio (Composition, Electroacoustics, Computer Music).
In 1970 and 1971 he was a répétiteur at the Salzburg Festival. In 1973/74 he worked freelance at Radio France and the ORF. From the autumn of 1973 Ager was first assistant to the chair of Music Theory and then in 1997 took over the chair of Music Analysis at the Mozarteum University.
Travel abroad for study and work took him to Stockholm (1974), San Diego, USA (1977), Hamilton, N.Y. (1979, 1981) etc.
From 1977 on he established, as its president and artistic director, the contemporary music festival ASPEKTE SALZBURG, devoted primarily to international new chamber music but also including performances of opera and ballet.
