Silvio Dalla Torre, Rostock (double bass)
Silvio Dalla Torre
comes from a German-Italian family and was born in Kempten/Allgäu. After
studying music in Augsburg, Munich and Vienna he worked for 20 years as solo
double bass player in opera and symphony orchestras in Germany, Switzerland and

played an active part in several of the chamber music ensembles he established
there. At the beginning of 2002 Dalla Torre was appointed Professor of Double
Bass and Chamber Music at the Rostock School of Music and Theatre. His
extensive research and analyses of "historical and modern double bass
playing techniques" led to the establishment of what has become a
much-discussed method which owes its origin to a wide range of influences. Dalla
Torre has given master classes both in Germany and all over Europe, in the USA,
Canada and China. As a chamber musician and soloist he appears internationally,
both on the double bass and the bassetto. This is a bass violin with fifth
tuning that Dalla Torre researched and helped to design. In 2004 Silvio Dalla
Torre founded the music publishing house sidato-verlag. He has often been a
juror in international competitions and also works as a journalist producing
specialist articles on many topics concerned with the double bass. He has made
it his mission to bring together the diverse double bass playing cultures and
sees the Double Bass Kaleidoscope as a suitable forum to stimulate and enrich
the international double bass scene.
