There are 30 stopped white oak pipes. ("c" below middle "c" to "f" at the top of the treble staff) The sound is soft, chiffy, liquid, and woody. It can be fairly easily tuned to a variety of temperaments with "a" at 440 or 415. The debut concert was a performance of the Corelli Christmas Concerto with 15 strings from the Riverside Chamber Symphony which I conduct. I am preparing a group of small scale 2 voice hymn tune arrangements appropriate for modest instruments like this one.
