The complex research works on Klaipėda Region Lutheran Psalms singing traditions has started at the Institute of Baltic Sea Region History and Archaeology, Klaipėda University some years ago, as a part of integrated studies on whole historical Lithuania Minor history and culture investigations. The main goal of such research project is to unify efforts of ethnomusicologists, historians, culturologists, linguists, confessional researchers and cultural anthropologists, interviewing local Lutheran people with special questionnaires, and this way collecting actual information about this culture phenomenon. The aim of this re-search is to find out the sources of vitality, local forms and intercultural (German-Lithuanian) relations of local Lutheran Psalm singing tradition, as well as its perspectives at present and for the future. The second aim was to find out and to elaborate generally wider research methods, possible not just for specialised (linguistic, ethnomusicological, etc.) investigations, but usable for complex interdisciplinary explorations. We have a great hope for interdisciplinary and socio-cultural anthropological perspectives here at present and in all the future.
