In 1823 his family moved again, this time to Paris. He wanted to go to the Conservatoire to study music but Luigi Cherubini would not let him in because he was a foreigner (i.e. not French). So he studied music theory privately with Reicha and composition with Paer. Soon he was asked to play the piano everywhere in Paris. He travelled to London. On his second visit there in 1825 he played to King George IV at Windsor.
