I've always wanted to do a history of the Spanish lyric course, beginning with medieval cancioneros and romanceros, going through Garcilaso, Fray Luis and San Juan, Quevedo and Góngora, Bécquer, JRJ, Lorca, Guillén, Claudio Rodríguez, María Victoria Atencia, and Olvido García Valdés. I'd probably put in some Latin American poetry as well. It would basically be the canon. Not that there's anything wrong with that. My course in the spring is similar, but emphasizes popular poetry in the anonymous traditions. You would really need two semesters: one for poetry with an author and another for poetry without.
