Earliest Compositions, K. 1a–d, 1761
Manuscripts in the hand of Leopold Mozart
The Mary Flagler Cary Music Collection
The four pieces for keyboard on these two leaves are Mozart's earliest known works, composed shortly after his fifth birthday. They are in the hand of his father and are written on the blank pages of a notebook that he used in tutoring Wolfgang and his sister Maria Anna (known as Nannerl) in music. The note along the left margin on one page reads: Compositions by Wolfgangerl, in the first three months after his fifth birthday. These leaves were discovered in London only in 1954, and their publication in 1956 was one of the happiest surprises of that bicentenary year.
