Bach Prelude no 1 in C + Gounod = Ave Maria

Henrik Kilhamn explains this well known piece that actually consists of two parts between the two composers. Bach uses one musical idea of the arpeggio pattern throughout the prelude and changes the harmony one step at a time, creating a wonderful sense of assuring and relieving. 130 years later, Gounod wrote a melody to the prelude as accompaniment, which is now known as Ave Maria.

Performance of Ave Maria: 8:39.
