The Mueller Family Schola, comprising Christopher Mueller, his wife, Constanza, and their three children — is an ensemble dedicated to singing polyphony and chant at the Roman Catholic Mass. The ensemble gave two concerts as part of World Youth Day 2016, in Krakow, Poland, and has sung at Masses throughout Poland, Italy, and the U.S. We were recently featured in Regina Magazine (click for a PDF version). Our repertory includes works by Allegri, Bębenek, Gregorian chant (in Latin and in English translation), Handl, Isaac, Lawrence, Lobo, Molfino, Monteverdi, Mueller, Palestrina, Praetorius, Ravanello, Różycki, Tallis, Tartini, Victoria, and numerous others.

Our ensemble has three principal goals: 1) to provide beautiful music at Mass, for the glory of God and the edification of the faithful; 2) to inspire others, both church choirs and families, to take up the study and performance of this wonderful repertory; and 3) to provide an education in music, liturgy, prayer, cooperation, and perseverance to the children of the Mueller family. We invite you to scroll down and check out our videos, to see (and hear!) what we're about. And please keep our family in your prayers, that our labors may be pleasing to the Lord.


Our family began singing together in 2011 (with parents and the older kids), and a serious family ensemble was something we always wanted to do. Our kids sang in the parish children's choir for a few years, which Christopher conducted, and with that training and experience in hand, our Family Schola could really take off in the latter half of 2015! Our ensemble was featured on Corpus Christi Watershed, in a piece which gives further details about our philosophy & motivation.

We had the great good fortune of being a part of World Youth Day 2016 in Krakow, Poland, where we sang as members of the choir at the English-language Masses (which Christopher conducted), and gave two separate concerts in Krakow. Following WYD, we went on pilgrimage to other places in Poland, and then a second pilgrimage through Rome and various sites in Italy; we sang at daily Mass during both. Our musical journey included these locations:
