The Missa Helvetica was commissioned by St Ursula's Church, with support from the Swiss Archdeaconry, for the Archdeaconry Choir Festival in 2006. This was held in Berne to commemorate the centenary of the building of St Ursula's. It was composed by Paul Leddington Wright.
It may be sung in churches within the Swiss Archdeaconry, and the version here is available for practice purposes only, and only for use in Switzerland.
To play it, you will need the Scorch plugin.
