Text in English & German. This book features 14 contributions treated diversity and exchange ratios of musical life in Northern Europe -- from Estonia to Ireland. The concert life with its fundamental institutions , the choral movement as a social and political phenomenon and the importance of musical theatre in the company of 19 Century are thereby brought into focus. Play an important role in questions of cultural identity formation of various national and social groups as well as processes of reception , which can be viewed in this context as a kind of cultural transfer. One concern of the present volume, it is finally, to take the "marginal" regions away from the "big" history of music in the spotlight and to show the network of interrelationships and transfers, belonging to a coherent cultural region -- whether in the field of musical life (house music, music in public spaces), music education or in the field of publishing, concert or club system.
