YourClassical's freebie of the day is composer Francois Couperin's Les Nations, 4th Ordre, "La Piemontoise": I. Sonade.
It's a little too heavy on the violin, at the beginning, for me. In fact, one characteristic of the composition is that the instrumentation, volume, tempo, etc. change from one to another quite frequently.
