Chopin is one of the composers who you know their music the moment you hear just one bar of it. Other composers who are like this are Mozart for example. One of the things that make me think that Chopin is lacking a bit in maturation is the fact that he hardly composed any works that are not for piano solo ! It is so strange that a composer with the geniousity of Chopin didn't compose any orchestral work. I don't know whether it was because he didn't want to or he didn't feel he can compose orchestral works. I think it is just a big question for music historians..... Why didn't Chopin compose any orchestral works??
He composed two piano concertos. I think those qualify as orchestral works.
No I don't qualify those as orchestral works. These are works for the piano mainly where the orchestra is in the background and mainly used for accompanying. An orchestral work is a symphony for example, where the instruments of the orchesetra are exploited and orchestrated.
Of course they are orchestral works. An orchestral work is one in which an orchestra is used. The fact that the orchestra is there to accompany the piano is largely irrelevant. The composer of a concerto still needs to understand how to write for each instrument and how they need to interact with each other.By your definition, what works other than symphonies would you classify as orchestral works? What about a mass? In a mass, the orchestra is present mainly to accompany the vocalists, but I doubt anyone would argue that the Missa Solemnis does not qualify as an orchestral work.
