Three Russian Airs With Variations, Op. 72
Trois Airs Russes Variés pour le Piano-forte et Violoncelle ou Violon Concertans, Op. 72, was written in 1812, while Ries was on tour in Russia with virtuoso cellist Bernhard Romberg. A virtuoso display piece for both instruments, it is a potpourri of three Russian tunes. Two cello parts are included: one as printed in the first edition, and one with fingerings and bowings by Martin Rummel.
