In my childhood, my mother used to play Mozart's Violin Concerto #3 in G major for my two sisters and me at bedtime every night; she had come across the notion that having a specific "aural setting" for going-to-bed would help us fall asleep better. It seemed to work. Years later when I first played in the orchestra for that concerto, I was afraid old associations would make me fall asleep!
Fortunately, I stayed awake.
But that concerto brings back good memories of bedtimes, especially the classic Isaac Stern recording that my mother used.
The opening of Beethoven's Ninth's Scherzo was used at one time for a radio news program--don't ask me which one! I've been trying for decades to remember...
And the first time I ever played in an orchestra (age 17, at the Nebraska All-State Fine Arts Camp in Lincoln), our program included the March from Saint Saens' Algerian Suite, the Evening Prayer from Hansel und Gretel, a "country" orchestral composition whose name and composer I'd have to look up, and the Finale from Beethoven's Fifth. Any one of those pieces, especially the Evening Prayer, takes me right back to that heady virgin experience with an orchestra.
