Bach lived in Leipzig, Germany and did very little travelling. However, whenever musicians came through town, he would make a point of hearing them. So he wrote a vast array of music of different cultures including English Suites, French Suites, Italian Concerto, as well as a wealth of other music. He wrote weekly masses at the church where he worked. At one point, he was composing music for 3 different churches!
