Jerry, last month I heard "Pictures at an Exhibition" played by a 21 yr. old Japanese boy, 2003 winner of the Cleveland International Piano Competition. (There is a piano arrangement of this.) I thought he would levitate off the bench! Some of the parts were very, very big - trying to put an entire orchestra on the piano.

There are several "pieces," or "pictures" with walking music between them:
Promenade
Gnomes
The Old Castle
Tuilleries
Bydlo (The Oxcart)
Ballet of the Unhatched Chicks
Samuel Goldberg and Schmuyle (Tow Polish Jews)
Promenade
Limoges
Catacombs
The Hut on Fowl's Legs (Baba Yaga)
The Great Gate of Kiev

Most people recognize the "walking music" (promenade) and the last "picture," The Great Gate of Kiev. Both show up as background music in ads, etc. One local interior design business here in town uses the promenade theme in their TV ads - very sophisticated sounding.

The fight song for the University of Texas (Hook 'em Horns!) is very similar to the Great Gate (not identical). If you ever see that band, watch as they march with long strides to that music.
