The Tenso network was founded in 2003 by four renowned European professional chamber choirs from Germany, France, Latvia and the Netherlands, in order to reinforce, extend and promote professonial and amateur choir practice in Europe, to contribute to the creation of new, innovative repertoire, and to create a stronger, more visible position for choir music in the European cultural arena. The network now consists of seven members and three candidate members, and it has found a solid base for many of its activitities.In the project Tenso NORTH+SOUTH 10+11 we aim to intensify the existing cooperation, extend it to a larger group of excellent professional chamber choirs, work closely together with amateur and semi-professional choirs, and use the acquired momentum to realize a renewed appraisal of (contemporary) chamber choir music in European culture. For the upcoming period, we want to focus especially on:- extending the network to the Mediterranean and Balkan area (leading up to Tenso Days in Marseille 2011)- opening the created internet database to others and linking it to other music databases- creating and distributing new repertoire for chamber choir- mobility for (young) singers, conductors and members of management teams
