The slow movement of a piano concerto by this composer ends its chromatic first phrase with the flutes playing a pattern of a grace note falling to a held note down an octave on “E, D, C-sharp, B.” Hilary Hahn’s album Paris features this composer’s first violin concerto, whose opening theme is marked sognando. A massive cadenza is found in this composer’s second piano concerto, which features a passage marked triple-forte and colossale. This composer’s C major third piano concerto contains a theme (10[1])and variations and opens its first movement with a lyrical solo for the first clarinet. Despite a reputation for dissonance from his Visions fugitives, this composer channeled Haydn in his Classical Symphony. For 10 points, name this Russian composer of the ballet Romeo and Juliet and the children’s piece Peter and the Wolf. ■END■
