Brother, Can You Spare a Dime?
The song has unusual structure for a Broadway song. Firstly, rather than starting in a major key, as most Broadway songs do, it begins in a minor key, which is darker, and more appropriate for the Depression. When discussing the prosperous past and building the railroads, the song jumps an octave and moves briefly into a major key, evoking energy and optimism. It then reverts to a minor key in the word "time" in the line "Once I built a railroad, made it run / Made it race against time," marking the end of prosperous times, and changing to a wistful mood. The song then ends, not on a note of resignation, but with anger – repeating the beginning (as is usual for Broadway songs), an octave higher, but with a significant change: the friendly "Brother, can you spare a dime?" is replaced with the aggressive "Buddy, can you spare a dime?"
