As mentioned earlier, the contest is open only to the grand prize winners of the six-member European choral competitions in the previous year. In other words, if a choir wins the grand prize in any of the six cities' choral contests, it is eligible for then next year's GPE. Consequently, this also means that, unlike other choral competitions, the GPE does not solicit participants to the contest; no choir may directly apply or audition in order to join the GPE. If an eligible choir backs out, a substitute choir may take its place; as a penalty, any choir that backs out will not be eligible to compete in any of the six qualifying contests for the next year.
