After living for a while in Germany, where he pretended to study law, he went to Paris but fared badly for a year or two. In 1832 in Paris he shared rooms with the Moravian violin virtuoso Heinrich Wilhelm Ernst. He was eventually successful in becoming a high-level virtuoso, giving thousands of concerts. In England alone these included 274 in 1837, during which visit he also travelled to some of the more remote parts of Britain. Bull became very famous and made a huge fortune. He is believed to have composed more than 70 works, but only about 10 are known today. Best known is "Sæterjentens søndag" ("The dairymaid's Sunday").
