This piece’s coda is interrupted by two measures of an unaccompanied right hand melody, marked slentando, that begins “tied pickup B-flat, A-flat, G-flat, down to C, up to F.” This piece’s composer apocryphally improvised it while dreaming that he was drowning in a lake. This piece’s middle section in the enharmonic parallel C-sharp minor (-5[1])uses low, sotto voce quarter note (15[1])dyads to evoke the plainchant its composer heard at a monastery in Valldemossa. This piece opens with the slurred, sostenuto 4/4 melody “dotted eighth note (*) F, sixteenth note D-flat, (-5[1])low half note A-flat” (10[1])over a dominant pedal that is respelled in its middle section. (10[1])This longest piece in its composer’s Opus 28 was written during a vacation in Majorca with George Sand. For 10 points, name this Chopin prelude whose repeated (10[1])A-flat (10[1])evokes (10[1])a type of (10[2])weather. ■END■ (10[4]0[1])
