Заголовок: Kadenz zum Klavierkonzert op. 19
These fragments are all found in the Kafka Miscellany in the British Museum. There are 3 principal fragments which, according to Joseph Kerman, belong to 2 different cadenzas. The 1st & earlier cadenza is found on Kafka pages 89 & 46; they are both on the same kind of paper which was used in 1792 & 1793, and likely contemporaneous. The other cadenza is found on Kafka 45. The 3rd chunk is found on Kafka 45, and as Kerman notes, is probably for a distinct cadenza. It is on a different paper which has been dated to about 1793-1796.
