This word titles a “Song” subtitled “Maytime in Sussex” by Arnold Bax written in anticipation of Princess Elizabeth's 21st birthday. Elgar's String Quartet in E minor quotes (15[1])from a G major allegretto “Chanson” named for this word. A scene whose title begins with this word includes the description “Acacias and palm trees” and features a secondary quarter-note string melody “G-sharp, F-sharp, (15[1])E, F-sharp, G-sharp.” The notes “B, G-sharp, F-sharp, E” (15[1])are played by (15[1])(*) solo flute and oboe to open the main pentatonic theme of a scene whose title begins with this word. The Moroccan desert is depicted in an Act IV scene whose title begins with this word that comes after “The Death of Åse.” For 10 points, name this word that, per the title of a scene from Edvard Grieg's incidental music to Peer Gynt, describes a “Mood.” ■END■
