The Fons de Música Tradicional at the Institució Milà i Fontanals (CSIC-IMF) in Barcelona has more than 20.000 melodies, copied on paper, collected between 1944 and 1960 throughout Spain; most of them were compiled through the 65 folkloric missions and 62 notebooks presented to competitions organized by the Folklore Section of the former Instituto Español de Musicología of the CSIC, in which 47 researchers participated.
Launched in 2015, Una colección de patrimonio musical español/Una col·lecció de patrimoni musical/A Spanish collection of traditional music heritage is an open-access database comprising digitized materials of the music collected in the competitions and missions of Andalusia, Balearic Islands, Castile-La Mancha, the Castile and León region, Catalunya, Galicia, the Murcia region, and the Valencian community; more materials from these and other Spanish regions will be incorporated later.
The site can be navigated in Spanish, Catalan, or English; searches may be organized by source, location, researcher, informant, genre, or title. Audio files of the melodies will eventually be added.
Above, notation for the instrumental tune Paciendo el rebaño; the full record, which includes other visual materials, is here.
