The vocal ensemble Gemma specializes on Gregorian chant from medieval Scandinavian sources but also perform church music from the earliest Western polyphonic repertoire from the 12th and 13th centuries. The repertoire is mostly based on the ensemble’s own research in archives and libraries and presents music that often not has been heard since the Middle Ages.

The singers have all specialized in early music through their studies in France, the Netherlands, Denmark and Sweden. They also work with other early music ensembles such as Diabolus in Musica, Dialogos, Musica Ficta, Laude Novella and have performed in numerous Europeian countries. In 2014 a collaboration with the Belgian ensemble Psallentes was initiated.

The ensemble also collaborates with museums in order to illustrate exhibitions and create soundscapes. Their music can be heard at the exhibitions Sveriges historia (History of Sweden) at the National Historical Museum in Stockholm and Skaramissalet och andra medeltida handskrifter (The Skara Missal and other Medieval Manuscripts) in Skara.

In 2014 they recorded their first cd: the Torstuna Missal with music from the Dominican chant tradition. The recording was a production together with ensemble Psallentes.

Gemma also holds courses in medieval vocal music.

Director of the ensemble is Karin Strinnholm Lagergren.
