     Welcome to your favorite show-"Music Land "! This month we are going to have some special

shows on Bach, the Father of Music.

     Johann Sebastian Bach was born in Germany (德国) in 1685, During his life, Bach wrote a lot of

music for the church (教堂) and for his students, but he himself did not keep his own works (作品)

carefully.  Luckily, his second wife (妻子) saved them for him, so today we can still remember Bach

through his music.

     Bach married twice in his life and had 20 children. He loved his family very much. He wrote music

for one of his daughters to tell her that too much coffee was bad for her health. I am now going to play

a song for you from this interesting Coffee Cantata. And we will hear more about Bach after this song.
