Extra Information
|
Regarded as doubtful, relegated to Appendices in Köchel 6th edition, and Supplement (Doubtful works) in NMA X/29/2, pp.225–45. "4-movement Sonata published by Thonus in Leipzig in 1798 and then others as Mozart; 1806 issued by Kühnel attributed Sonata to August Eberhard Müller--Sonata's 2nd movement set of variations form K450, 4th movement used themes of K450, 456, 595, other movements original; K1 listed in Anhang for transcriptions; Nottebohm and K2 believe Sonata to be work of Müller; K3 moved Sonata into main section with speculative dating Aug 1786; K6 placed 1st movement and 3rd movement into Anhang C section as a doubtful work. An analysis of Sonata with works of Müller (including 4 movement structure) shows more likely work by Müller than Mozart (Marguerre-MISM 1978)" [1]
