I like classical music, too. I first got into it in High School, thanks to hearing Un Bel Di from Mme Butterfly in a Shirley Maclaine movie. Also, there was an excellent alto singer in my choral class (Clara). In college, I was introduced to Beethoven, Vivaldi, Bach, Chopin, Aaron Copland and George Gershwin.
Today, my favorites include:
Chopin's Prelude No. 4, Op. 28 in Em, and his Prelude No. 24, in Dm, (also, Opus 28) Beethoven's 7th Symphony, 2nd Movement (the Allegretto) Vivaldi's Concerto for Lute and Mandolin in D Major Copland's Billy The Kid Ballet Suite Gershwin's Rhapsody In Blue
