At the age of four Mozart astounded his father with his understanding of the Piano. His first works were simple dance settings written when he was five at which point his musical abilities were developing at a tremendous speed. The earliest pieces are recorded in the music book for Maria Anna Mozart the so-called 'Nannerl-Notenbuch'. These pieces are ideal for elementary teaching. Apart from the popular minuets which form part of every Piano beginner's repertoire the edition also contains expanded individual settings such as the fragmentary piano piece in B flat major KV 9b made playable by Robert D. Levin's edition and thus becoming a valuableaddition to the teaching literature.
