Perpetuum mobile (Weber)
Scored for solo piano (2 hands). The original part for the right hand is transferred to the left, while the new right hand part is Tchaikovsky's own.
Movements and Duration
There is one movement (C major, 332 bars), lasting around 4 to 5 minutes in performance .
The story of the arrangement of the Sonata is told in reminiscences by Mariya Dulova and Nikolay Kashkin. Mariya Dulova recalled: "While my mother-in-law, Aleksandra Yuryevna Zograf-Dulova, was a student at the Conservatory [in 1866], she studied under N. G. Rubinstein and Pyotr Ilyich. While playing with her right hand she began to cry in front of Pyotr Ilyich who laughed and told her: "Don't cry, Sashenka, I will write you an etude for the left hand. That is how it came to be done" .
Nikolay Kashkin's account of the arrangement is different "Students in Tchaikovsky's harmony class worked very hard and with apparent success... Yet. N. G. Rubinstein overestimated their abilities to the detriment of the former, and in his piano class he set the harmony students the task of harmonizing the rondo from Weber's First Sonata, with the principal part in the bass. In the end this could not be done satisfactorily, and so Tchaikovsky did it himself. It seems that P. I. Jurgenson printed it then, or perhaps a little later".
Tchaikovsky's autograph score is now preserved in the Klin House-Museum Archive (a1, No. 95).
The manuscript score of the arrangement carries a dedication to the pianist Aleksandra Zograf (1850–1919).
