Gee, it’s hard to pick. All the jellies before me have named some great choices! Here are some additional favorites of mine:
Handel’s Messiah
“O mio babbbino caro” from Gianni Schicchi by Puccini
Strauss: Alpine Symphony and Also Sprach Zarathustra
“Va’, pensiero” from Nabucco by Verdi (chorus of the Hebrew slaves)
Jupiter movement from The Planets by Holst
Eine Kleine Nachtmusik by Mozart (the melodic invention never ends!)
Blue Danube waltz by J. Strauss (ditto)
Mahler – Symphony No. 4, last movement (depicts the joys of heaven, the music is heavenly!)
“Glück das mir verblieb” from Die Tote Stadt by Korngold (a simply haunting melody; on a flight once, I listened to it over and over)
Entrance of the Gods into Valhalla from Das Rheingold by Wagner
Transcendental Etudes by Liszt
Grieg – Piano Concerto in a minor
Grieg- Peer Gynt Suite, first movement
If you like it loud, how about these:
Mahler – 8th Symphony (“Symphony of a Thousand”)
Gurrelieder by Schoenberg
Turangalila Symphony by Messiaen
The Creation (parts of it) by Haydn
Enjoy! That reminds me, I’m going to put on some of these right now!
