Solemn Mass is our particularly festive form of the Sunday Eucharist. We celebrate it every Sunday and holiday at 9:00 in the morning. What gives Solemn Mass its extraordinary character is its musical framing: be it large orchestral masses featuring St. Michael's Choir; be it mass celebrations accompanied by a chamber choir, smaller instrumental ensembles or the Choralschola; be it our organ joining forces with another instrument.
