Parishioners stood or knelt during services. The nave is a long and tall structure interspersed with four small altars, two on each side, each with a niche for a statue above it. The statues were of Mexican Baroque design. People gathered at them to pray and leave candles. The nave had a white plaster interior, decorated with colorful designs such as scallops near the ceiling. There was floral and geometric stencil work on the walls and arches in the church, in addition to colorful decorations in and around the niches.

THE CHOIR LOFT Just inside and above the main entrance was a balcony, approximately 10 feet in depth, that spanned the width of the church. It would have held members of the choir consisting of about eight to ten musicians playing instruments such as trumpets, oboes, bassoon, flute and zither. There would have been approximately the same number of singers who would have sung in Latin, Spanish, and O’odham. The music must have been beautiful due to the excellent acoustics of the church. https://www.nps.gov/places/tumacacori-c ... tent=small
