For 10 points, name this work based on a namesake Spanish dance by Maurice Ravel.
This work grew out of an aborted commission by Ida Rubenstein to orchestrate a set of Albeniz piano pieces.  Arturo Toscanini popularized it in America, but he and the work's composer argued about its tempo. Originally conceived as a ballet, the main melody is played in C major, with other instruments playing the same tune at the same time in other keys. Shostakovich's Leningrad Symphony drew many comparisons to it, especially the extended use of a repetitive snare-drum pattern.
