Basic familiarity with Gregorian chant and at least light experience singing in a schola are required for this role. You do
not need virtuosic skill or an extraordinary voice. Singers will be expected to attend one rehearsal prior to the day of the pilgrimage, at a mutually convenient time. (And it goes without saying, it is not possible to both sing in the schola and serve at the altar; cf. the next question.)
Additionally, singers in the schola will be asked to help lead the group in the singing of hymns during the pilgrimage itself. These hymns will be included in rehearsal.
