Thomas Forrest Kelly has identified and collected the surviving sources of an important repertory of early medieval music, the so-called Beneventan Chant used in southern Italy in the early middle ages, before this area's adoption of the now-universal Gregorian chant. Because the Beneventan Chant was suppressed during the eleventh century, the music survives mostly in fragments and palimpsests, and the process of restoring the repertory piece by piece is the focus of the studies here.
