The instrument associated with St. Margaret Mary R.C. Church: Opus 21
Martin Ott Opus 21 was a 16-stop, 18-rank mechanical organ built in 1982 for St. Margaret Mary Catholic Church in Naperville. The free-standing red-oak case stands at the front, to the right of the altar, with its attached keydesk angled slightly toward the congregation.
The surviving chronology begins with 1982 beside Opus 21. No day, month, or event label accompanies that year. St. Margaret Mary R.C. Church in Naperville, Illinois fixes the historical setting, but a contract or dedication programme would be needed for a tighter sequence. The entry does not answer present access or condition.
The room question behind Opus 21
For Opus 21, the geographic anchor is St. Margaret Mary R.C. Church in Naperville, Illinois. The church setting gives the project a clear institutional frame, yet it cannot stand in for evidence about liturgy, repertoire, access, or sound. Unless a recital, hymn event, placement, or acoustic observation appears in the project history, those details should remain unstated.
Reading the numerical outline for St. Margaret Mary R.C. Church: Opus 21
A total of 16 stops and 18 ranks is attached to Opus 21. The first figure belongs to the console controls and the second to sets of pipes, so the numbers should not be treated as synonyms. There are 2 additional listed ranks in the Opus 21 totals. That is compatible with stops drawing several pipe rows, though the short overview does not say which ones. They provide a useful scale marker while leaving voicing, wind pressure, pipe count, and division layout unresolved.
Touch, control, and the missing technical detail: Opus 21
For Opus 21 at St. Margaret Mary R.C. Church, the action is recorded as mechanical. That tells us how the key command began its journey to a pipe valve; it does not tell us how the stops operated, how the console sat in the room, or how the mechanism has aged. Historic action type and current playing condition are not the same claim.
What the project facts suggest, cautiously: Opus 21
For St. Margaret Mary R.C. Church, the strongest surviving clues are concrete: it was placed at the front right and its case was angled toward the congregation. The worship setting makes pipe placement and support for singers relevant to the design. The archived account does not describe the complete tonal balance or document day-to-day use. Contemporary parish records, a stop list, or a dedication booklet could supply that missing musical context. The listed 16-stop, 18-rank scale remains the numerical boundary for this reading.
What happened after the organ was built: Opus 21
Composer and organist Richard Proulx is named as consultant. The archived extract gives no dedication date, performer, relocation, or later alteration. Its project history is limited to the front-right placement, the slight turn intended to improve projection, the oak case, and Proulx's advisory role. The source does not describe another position before or after this installation.
