It was a characteristic of Frederick Corder to encourage his pupils to write their own parts to duet with established classics. Thus Corder brought out a set of piano pieces that, on two pianos, could be accompanied by Czerny’s School of Velocity
. York Bowen wrote a second piano part to accompany Beethoven’s 32 Variations in C minor. In similar vein he produced this viola obbligato for the first movement of Beethoven’s ‘Moonlight’ Sonata, though it is not possible to determine its date. It seems likely it was a student or pre-First World War piece. Only 57 bars of Bowen’s manuscript survive, and the last twenty-odd have been completed by Lawrence Power, following the example set by Bowen in the earlier part of the movement.
