A work called the "Hexameron" is included in catalogues of Liszt's compositions, although he only contributed part of it. It is the march from Bellini's "Puritani" with six variations, written by six pianists and originally played by them on six pianofortes, five of them full grands, while Chopin, whose variation was not of the bravura, kind, sat at a two-stringed semi-grand. Liszt contributed the introduction, the connecting links and the finale of the "Hexameron."
The "Années de Pèlerinage" were published in three divisions, extending in point of time from 1835 to 1883. They are a series of musical impressions, as the titles indicate--"Au lac de Wallenstadt, Pastoral," "Au bord d'une source, Sposalizio" (after Raphael's picture in the Brera), "Il Penseroso" (after Michael Angelo). Many of these are adroit and elegant in the treatment of the pianoforte, and at the same time beautiful as music. The "Harmonies" are partly transcriptions of his own vocal pieces, partly musical illustrations to poems. Among them is the familiar "Cantique d'Amour," and the "Benediction de Dieu dans la solitude," of which he himself was very fond. William Mason says that at the Altenburg a copy of it always was lying on the pianoforte, "which Liszt had used so many times when playing for his guests that it became associated with memories of Berlioz, Rubinstein, Vieuxtemps, Wieniawski, Joachim." When Mr. Mason left Weimar he took this copy with him as a souvenir, still has it, and treasures it all the more for the marks of usage which it bears. The "Consolations," which, as Edward Dannreuther says, may be taken as corollaries to the "Harmonies," are tenderly expressive pianoforte pieces.
The Études bear the dates 1827, 1839 and 1852, and as they are in the main progressive editions of the same pieces, they represent the history of pianoforte technique as it developed under Liszt's own fingers. In their earliest shape when issued in 1827, they were but little different from the classical Études of Czerny and Cramer. In their latest shape they form the extreme of virtuosity. Indeed, these three editions are three giant strides in the development of pianoforte technique. Von Bülow's coupling of the Étude called "Feux Follets" with the A flat study (No. 10) of Chopin already has been quoted under that composer. He considered it even more difficult. Schumann called the collection "Sturm und Graus Etuden" (Studies of Storm and Dread), and expressed the opinion that there were only ten or twelve pianists living who could play them. In the Étude called "Waldesrauschen" will be found some ingenious double counterpoint. The theme is divided into two portions, a descending and ascending one, which later on appear together, with first one and then the other uppermost. Other titles among the Études are "Paysage," "Mazeppa" (a tremendous test of endurance), "Vision," "Chasse-neige," "Harmonies de Soir" and "Gnomentanz." Through Liszt's transcriptions of some of the Paganini pieces in the form of Études, which include the famous "Bell Rondo" from one of the Paganini concertos, this piece, for example, now is far better known as a pianoforte composition than in its original form for violin.
