In his early youth Bach copied pieces by other composers to learn from them.^[141] Later he copied and arranged music for performance and/or as study material for his pupils. Some of these pieces, like "Bist du bei mir" (not even copied by Bach but by Anna Magdalena), became famous before being dissociated with Bach. Bach copied and arranged Italian masters such as Vivaldi (e.g. BWV 1065), Pergolesi (BWV 1083) and Palestrina (Missa Sine nomine), French masters such as François Couperin (BWV Anh. 183), and closer to home various German masters, including Telemann (e.g. BWV 824=TWV 32:14) and Handel (arias from Brockes Passion), and music from members of his own family. Then he also often copied and arranged his own music (e.g. BWV 233–236), as likewise his music was copied and arranged by others. Some of these arrangements, like the late 19th-century "Air on the G string" helped in popularising Bach's music.
