Historically the CHMTL has focused on gathering and disseminating texts on music and their scholarship. Today our activity aims to support projects researching a range of documents pertaining to the history of musical thought and its deep links with the other arts and sciences from the Middle Ages onwards. Our earliest projects, first and foremost the Thesaurus Musicarum Latinarum, made pioneering use of technology and the internet by making freely available hundreds of music treatises in Latin dating from the Late Antiquity. In the twenty-first century CHMTL aims to continue to be at the forefront of research in computer-assisted studies of the music of the past.
