Here is a YouTube video that shows the Amy Beach Piano Concerto score as it is played. The first movement, 18 minutes, is noteworthy for its very expansive sonata structure. The finale "scioltezza" means with agility. The music is noteworthy in sounding laid back but erupting into powerful, even violent, climaxes. The work has more orchestral passages than usual for a piano concerto, almost as if a "concerto for orchestra with piano". The piano writing has some similarity to Brahms and Liszt, but looks ahead to Rachmaninoff. Beach has a way to take mundane, almost pedantic or perfunctory themes (which sounds like an odd thing to say because she often uses her own songs or other folk songs in her large works), and make them interesting. In her music, the "development" is everything Although this concerto is hardly every played, it is easy for the "ear" to learn and sounds familiar after two or three playings; like D'Albert's big works, it has its own internal logic that seems quite compelling. .
A male pianist should play this work with the New York Philharmonic the weekend before the general election, if we wind up with Hillary Clinton v. Donald Trump. Performing the work could make a political statement.
