 These lodgings were located conveniently close to several concert rooms, and to the residences of both J. C. Bach and Carl Friedrich Abel.Bach, a son of Johann Sebastian Bach, soon became a family friend; Nannerl later recalled Bach and the eight-year-old Wolfgang playing a sonata together, taking turns to play a few bars individually, and that "anyone not watching would have thought it was played by one person alone".There is no record that the Mozarts met Abel, but Wolfgang knew his symphonies, perhaps through the medium of the annual Bach-Abel concert series, and was much influenced by them.
