The haunting Gallego-Portuguese cantigas de amigo are an all-but-lost piece of a love lyric tradition dating back to the ninth-century. Hundreds of medieval texts have survived but until the early 20th century, the melodies of these songs were forgotten. In 1914, six songs from the 13th century with notated melodies were discovered hidden within a book binding by a Madrid bookseller. These songs are part of a dialogue between oral and written music that is still present in folk tradition, fado and composed music. For more than twenty years, vocalist and educator Cristi Catt has researched the cantigas and their cousins in oral and written traditions. A two-time Luso-American Foundation grant recipient, Catt has traveled to Portugal and northern Spain to further her studies and immerse herself in the culture and environs of these songs. Catt will share her experience with these songs as a performer, improviser, arranger and collaborator with composers and fellow improvisers. The audience will have the opportunity to hear, sing and improvise with the melodies and modes of these unique songs.
