A long time ago, a boy named Sebastian was born into a family of musicians. He heard music everywhere, especially in his own head, and he wrote down what he heard. Sebastian married, raised a family, and wrote more than a thousand pieces of music. He also created a little book of music especially for his wife, Anna Magdalena, so that in the evenings the whole family could make music together. Hundreds of years after his death, Bach's music is heard and played all over the world. Manypeople think it is some of the most glorious music ever written. And today young students--like Bach's own children--can learn to play the music from Anna Magdalena's notebook.
