 Following the death of Liszt's father in 1827 and his hiatus from the life as a touring virtuoso, Liszt's playing likely gradually developed a more personal style.One of the most detailed descriptions of his playing from that time comes from the winter of 1831–32, when he was earning a living primarily as a teacher in Paris.Among his pupils was Valerie Boissier, whose mother, Caroline, kept a careful diary of the lessons.
