Solemn Mass
Solemn Mass was the most common before 1962. The Priest would be assisted by a Deacon and Subdeacon. Including a MC, Thurifer, two Acolytes, and some servers to carry torches at the Canon. All parts are sung and chanted. The Subdeacon reads the Epistle, while the Deacon chants the Gospel. The Priest sings the rest of the Mass.
An SSPX Chapel had solemn Mass for the feast of the Assumption.
