Morceau de Concert - Grandes Variations de Bravoure pour Piano sur la Marche des Puritains de Bellini, composees pour le Concert de Mme la Princesse Belgiojoso au Benefice des pauvres - by Liszt, with Sigismond Thalberg (1812-1871), Johann Peter Pixis (1788-1874), Henri Herz (1803-1888), Carl Czerny (1791-1857) and Fryderyk Franciszek Chopin (1810-1849)
AKA Hexameron Variations
Yes dai bread!
The Hexameron variations were comissioned by Princess Belgiojoso who had six of the best virtuoso pianists write their own variation on a march theme from Bellini's opera, "I puritani." Liszt, Chopin, Thalberg, Czerny Pixis and Herz all contributed. The six composers, hence "Hex" contributed their variation but never played it together in public. Liszt was the only one who assembled the variations, bridged them together, augmented them, (even taking out some bars from each variation to bettter link them together).
Yes, the work is collaborative and considered a collection of variations by six different composers. But essentially it was Liszt who stitched them together into a complete tapestry and he played them throughout his virtuoso touring days. If you look at any recording or any concert bill back in the 1830s-40s the "Hexameron variations" are attributed as a Liszt composition.
It's such a splendid piece of bravura romanticism; one of my favorite actually and therefore I based my forum name on it. I thought that would have been the obvious indicator, which is why I mentioned the "Purloined Letter." The hardest thing to find is right in the open (my name).
