This portable continuo is made in two sections to facilitate transport. When seated at the keyboard the organist has an unobstructed view of the conductor. The oversized music rack was designed in collaboration with Nelson Vigneault, for, as he says, "One never has enough space for a few more sheets and a sharp pencil".

Opus 113 

Robert Bergt Memorial Organ
Concordia Seminary
St Louis, Missouri

Year of construction 2011

The continuo organ was build in late 2011 to become a rental instrument but was purchased upon completion by the Concordia Seminary in St. Louis.

Robert and Lori Duesenberg gifted this instrument to Concordia Seminary in honor of Robert Bergt.

In 1968 Bergt founded the American Kantorei, a choral-instrumental group specializing in the music of J. S. Bach. He conducted the concert series Bach at the Sem until his death on July 26, 2011. His friend Robert Duesenberg noted: "His music making is now silenced, but his ministry reached many and will live on in memories."

The Robert Bergt Memorial Continuo Organ was dedicated on December 5, 2012 at a Bach at the Sem performance of Bach's Mass in B Minor: Credo, Sanctus, Benedictus, and Agnus Dei. Joan Bergt, widow of the late Robert Bergt, played the continuo part.

Continuo pipe organ:

Martin Ott has built several Continuo organs over the years. These small pipe organs are more than simple practice instruments. They are designed to meet the standard needed for music ensemble, orchestra works and choir touring. In the tradition of his uncle, the reputable German Orgelbaumeister, Paul Ott, these Continuo organs are made to suit on-location performances.

According to Martin Ott, Paul Ott gave to the small pipe organ the appellation "CONTINUO"—and was the first to use it—to describe an instrument in size between a portative and a positive organ. The Paul Ott instruments were tailored to fit the popular 1950-60 Volkswagen van.

Martin Ott's Continuos have casters and often carrying handles. On Opus 113, the bottom blower section of the instrument has its own set of handles, and can be separated to ease transport. All the pipes are locked in secure position for transport. The pipes are elegantly visible, which is not often the case for box organs. The generous and solid music rack on Opus 113 allows the performer to write annotations. The partially open design of the instrument's upper cabinet provides a clear sight line to the orchestra conductor during the performance. The case is made of American walnut.
