Opus 4 for the University of Oregon School of Music

Opus 4 is an 13-stop mechanical-action practice instrument we built for the University of Oregon School of Music. It is replacing an 8-stop Flentrop damaged in a sub-basement flood in late 2007.

We used several ranks of pipes and some action components from the Flentrop to provide a nicer, more tonally complete instrument.

The disposition is as follows:

Manual I

8' Principal (wood)*
8' Gedackt (metal)
4' Octave (wood)
4' Flute (metal)
2' Principal (metal)

Manual II (expressive)

8' Oak Gedackt (wood)
8' Rohrflute (metal)
4' Koppelflute (metal)
2 2/3' Nasard (metal)
8' Regal (metal)

Pedal

16' Soubass (wood)
8' Gedackt (Man I)
4' Rohrflute (metal)

* to be installed Summer 2012
