Granados was not only very knowledgeable about forms, as demonstrated
by the fact that the concerto's first movement alone lasts nearly
twenty minutes, but his treatment of the orchestration and his concept
of the concerto genre, apart from being very idiosyncratic, are
totally different from what Granados had written till then. This
entailed the need to perfectly master orchestral writing, as well as
the treatment and knowledge of the instruments and orchestration. He
had acquired these facts thanks to his personal experience as a
soloist pianist and at that time also as an educator through the
concertos by Beethoven, Chopin, Liszt, Saint-Saëns, etc. that he made
his students study.
