One composer’s penultimate work in this musical genre opens with an arpeggiated whole note C-sharp minor seventh chord that resolves into a whole note F-sharp dominant chord. That B major work in this genre was published alongside an E major one in its composer’s Opus 62. An earlier work in this genre opens with the right-hand notes “F, E-flat D-flat, down to F, up to A-flat” over an arpeggiated (*) D-flat major chord in the left hand. A work in this genre dedicated to Marie (-5[1])Pleyel opens with the right hand leaping from B-flat up to G. The compositions in a composer’s Opus 27 and Opus 9 are in this genre. For 10 points, name this genre of 21 works by Frederic Chopin intended to evoke the night. (10[1])■END■
