The 12 cellists of the Berlin Philharmonic (Die 12 Cellisten der Berliner Philharmoniker) are 14 cellists, members of the Berlin Philharmonic as the name implies, who perform and record as an all-cello ensemble. The group first took stage on Easter Monday in 1974 at the Salzburg Mozarteum. Among the pieces they have recorded, Klengel's 'Hymnus' is an example of how each individual in a 14-cello choir can contribute a vital part of a musical whole.
