Hans Leo Hassler (1564-1612) was an important German composer, organist and madrigalist of the Renaissance. I have chosen the 'Ricercare 5to tono' to explore the musical diversity of the instrument from Norrfjärden (SE) in the truest sense of the word. Augustine's VO has created the Hauptwerk format of the sample from the replica built in 1997 by Grönlunds Orgelbyggeri in collaboration with Gothenburg University of the organ of the German Church in Stockholm (Paul Müller, 1608), enlarged in 1622 and 1651, which was sold in 2 parts to the churches in Övertorneå and Hietaniemi. Another replica is located at the original site in Stockholm.
