Of course, it could be that this 'Allegro de Concert' is based on an unrealized concerto just as the Chopin Op.46 is, but on the score it statesCaprotti wrote:As far as Wolff, the example you give is really very similar to Chopin's op.46 and I don't see why it should be different (in the sense of being part of a full concerto, even drafted). If we don't have any source stating that Wolff had in mind to compose an entire work in three movements, then a research of a manuscript score seems to be uneseful.
"Cet Allegro est tire du Premier Concerto" which seems to imply that a true concerto did exist.
As we had all the other parts it was just a matter of giving the viola notes which filled out the harmonies appropriately, we didn't try to be creative with it and give the part a soloistic role.Caprotti wrote:How did you proceed for the viola part of Hertz n.4 ? i see that there are some hints in the score for two pianos, where the second piano is given the main orchestral voices.
