Traces of Music intends to be a comprehensive survey of all places in Europe with a relation to musical history, complete with the matching addresses, maps, compact commentary and illustrations. The data, collected by the Dutch musicologist Ed Tervooren, came across in all kinds of publications, in the Internet and during numerous ‘forages’ through a great deal of the field. This resulted in a vast amount of data, but some can become outdated and lacks are inevitable. The author makes an appeal to the public to provide him with other suited addresses and with essential additions, photos or critical remarks with regard to the given data.
