A La Puerta de Toledo
This is a very basic sevillanas accompaniment por cante (singing). The video link here is to the Chiquetete version of "A la Puerta de Toledo." (Click here for the lyrics.) I have (for obvious reasons) not transcribed the string sections, but once it gets going, you’ll hear how the guitar fits in.
The version I’ve written out here, while perhaps not the most interesting accompaniment ever, will get you through the song. Once you have the basic sevillanas rhythm down, you should feel free to accent, syncopate, and otherwise alter this basic schema. When accompanying a singer, of course, you will want to be sure that whatever you do adds to the cante. This might not be the best time for your craziest falseta, but accents, stops, passing notes, and bursts of rasgueado can do a lot for a performance.
On the other hand, listening to good cante (such as the version linked here) can also be a good way to learn how to embellish solo playing. By picking out a few melody lines and passing tones between chords, a simple accompaniment piece like this can stand on its own music-wise. This will not only make you a more versatile player, but is also a potentially good way to build out your dance accompaniment repertoire (without spending another six or seven grueling hours (or years) in Paco’s Obras Completas).
