The database provides researchers and the general public with the totality of the medieval songs in the Galician-Portuguese Songbooks, the respective images of the manuscripts, as well as the music (whether medieval or the original contemporary versions or compositions that take as a starting point the texts of the medieval songs). The base also includes succinct information about all the authors included in it, about the characters and places mentioned in the songs, as well as the "Art of Trovar", the little treatise of troubadour poetics that opens the Cancioneiro of the National Library.
