“Little Sister” is Rufus in high classical mode, with very symmetrical violin figures. This makes sense, as I am fairly sure that the song is–at least in part–about the relationship between Wolfgang Mozart and his sister, Marie (aka “Nannerl”). She was actually four and a half years older than he was, and he first became interested in music watching his father Leopold tutor her. She too was a musical prodigy (esp. on the harpsichord), and she too toured the courts of Europe with her father and brother. Occasionally, she even seems to have gotten top billing. Unfortunately, she got older, was forbidden by her father to marry the relatively impoverished man she loved, and forced to marry a rich old guy. She also wrote music, which her brother praised, although virtually none of it has survived. There’s even a French movie about her (which I haven’t seen yet). I bring this up, simply because some of the song’s lines actually make much better sense if you see them as being about Wolfgang and Nannerl.
