Madrigal

One way to get into early or pre-Common Era/pre-Baroque music is to try madrigals. They were Renaissance and early Baroque secular music that came from 1520's Italy. Many famous people worte them, like Palestrina and Orlande de Lassus.

Try the excellent piece "Altri canti d'amor, tenero arciero" ['Let others sing of love, the tender archer'] by major early Baroque transition music figure Monteverdi [1567-1643] from his Madrigals, book 8 [publ. 1638]. It's a lovely, light piece--perfect for this time of year.
