That was one of the funniest things I’ve ever seen. I had no idea that so many contemporary songs had the same chord structure, probably because I neither play cello nor guitar.
Gershwin. Rhapsody in Blue.
The slow movements of Rachmaninoff’s symphonies and concerti are often overlooked, compared to the other more popular movements. Here is the second movement from the Piano Concerto #2. I love how the piano is virtually making love with the woodwind section, one by one.
One of my favorite arias is “Dein is mein ganzes Hertz,” from Lehar’s *Land of Smiles. *Though it’s usually sung in the original German, Here is Pavarotti, singing it in Italian. It starts at 1:28.

Holy crap, was that ever fantastic 
Powerful, thundering classical pieces are usually what really do it for me. You know, stuff that sends shivers down your spine while simultaneously kicking you in the stomach. Pieces like the Dies Irae in Verdi’s Requiem and Tchaikovsky’s Marche Slave are among my all-time favorites in this category.
I’m also a huge fan of marching and martial music, and especially the choral stylings of the Red Army Choir. Soldaty V Pohod (a.k.a. “Off We Go!”, lit. “Soldiers, march!”) and Dyen Pobyedy (Victory Day) usually leave me breathless.
My contribution to this OP is from Handel’s Messiah, the Hallelujah chorus at the end of the piece. I love two versions of this wonderful work, both the original (edit nt: a thousand pardons…I just regained my computer & the sound isn’t hooked up yet, so I have to rely on youtube.) http://www.youtube.com/watch?v=nnHksDFHTQI. My other favorite is from The Young Messiah: http://www.youtube.com/watch?v=phhqYXTA5dA
I truly do rejoice.

10,001 aplolgies again, folks. I’m working between my newly re-enabled computer (no sound) & my husband’s laptop (has sound, is in another room). The “New Messiah Hallelujah Chorus” that makes me want to stand up & dance (while singing along at the top of my voice – not a good idea at 4:00 am) is: http://www.youtube.com/watch?v=tJq97Lgfufw Never mind the video. When the soprano hits that final high note on “…and Lord of LORDS!” I’ve never stopped being thrilled.
Love, Phil
I’ve only recently started educating myself in classical music, and I’ve found that I seem oddly attarcted to late 19th-century Slavic types - Brahms, Tchaikovsky and especially Dvorak Of the latter, my favorite piece is probably the2nd Movement of his Serenade for Strings in E. Pretty much the textbook definition of “hauntingly beautiful.”
Ignore the orchids.
So many of the things you’ve listed are so beautiful, but I wanted to mention one link in particular:
I’m not all that big on the jazzed up versions of The Hallelujah Chorus (they’re ok, but they just seem gimmicky to me), but your link to the original had sheet music to follow! I stood up and sang along for the first time in several years - and loved all 3 & 1/2 minutes of it. Thank you so much for finding that link - I added it to my favorites.
Anyway, thank you all for contributing thus far, and I hope more of you will continue to join in - this has been fascinating, to me at least.
But have you heard the Canadian Brass’s melding of the Hallelujah Chorus and When the Saints Go Marching In? You would never think it could work, but it does - spectacularly.
LINK PLEASE??? I really want to hear this!
The one that does it for me is the Carnegie Hall version of Sing Sing Sing by Benny Goodman. Accept no other version, the piano solo is in such beautiful contrast to the rest of the song it has made me cry since the first time I heard it, and it never fails to. Truly an incredible performance, and it’s an accident anyone kept a recording for me to hear. It only happened once.
I can’t find a place you can hear the whole thing, but you can hear Benny’s solo and Jeff Stacy’s solo on it here. I am listening to it now with tears streaming down my cheeks. I really can’t help myself. Go listen.
Here you go: Saints Hallelujah. Enjoy!
I certainly enjoyed the piano solo more than the rest of it. Although the virtuosity of all of it was impressive, only the piano solo was at all emotionally moving (IMO of course). But for me, even the piano was not as touching as it is to you. Very good, nonetheless.
That was fun, Brother Cadfael! 
Thanks!
Many of the above. A special seconding of “Daphnis and Chloe”.
Holst, Hymns from the Rig Veda, third group, for women’s chorus and harp. It has qualities similar to “Venus” and “Neptune” from “The Planets”.
Randall Thompson - Alleluia; the Last Words of David
Others far too numerous to mention.
When I was in high school, this was The Green Alleluia - the sheet music had a light green color. For many of us, it was our favorite piece. I have a Robert Shaw rendition on CD among a bunch of traditional choral Christmas corals. Sometimes I sing along with tears running down my face, same as with the Hallelujah Chorus. I never realized how much I loved that chorus until I didn’t have it anymore. I’ve joined a couple of semi-pro choruses (i.e. a few people are paid petty stipends, and the majority of us were singing for the pleasure of it) since, but it just wasn’t quite the same.
Here’s a link to a pretty good version on YouTube. Sorry for the religious still as the visual.
My all time favorite is The Four Seasons by Vivaldi, particularly Pinchas Zuckerman’s version. I like a lot of other kinds of music also, but baroque is best.
Over all I like baroque or Rennaissance music the best, but with a very few exceptions, the pieces that move me emotionally the most tend not to be baroque. Oddly, the individual works that really hit me are usually pieces that come from periods that, in general, I don’t really care for all that much.
I suspect that’s because I’m not really looking for emotional punch in my music as a rule. Baroque pleases me because it’s inherently “right,” as does Rennaissance music. But when something does reach out and grab me by the throat, then it sticks with me. Those pieces have usually been later works.
