Alexander Moosbrugger completed studies at the Vorarlberger Landeskonservatorium (organ and harpsichord), at the Universität Wien (Philosophy) and at the Staatliche Hochschule für Musik und Darstellende Kunst Stuttgart.
He primarily is writing in chamber ensemble settings, rarely doubled, preferring among other genres the string quartet.
In the foreground of a composition Moosbrugger interweaves auditory and non-auditory sources, establishing musical relations through translations of historical, sociopolitical and private points of reference, analysis of symbolic functions, the devising of intonations, and "reconceived instrumental practices".
Playing techniques manifest the "speaking" of musical images and are devised anew in each piece, or series of works.
