I built this Baroque-looking tromba marina using common materials. I whittled a piece of maple for the bridge. The body is a laminated sandwich of three pine boards--the front and back boards were routed out to make them thinner and more resonant. There are a lot of brass nails all around the soundboard edges. The back of the body is decorated in paisley decoupaged. The sound holes were simply drilled. The neck and head are unified: both were produced in the same single laminated piece that formed the body and were then cut and painted differently. The harmonic marks made on the neck were done in black and white paint with the names of the notes printed upside down beside them. At the tuning head, I used two guitar tuning gears: one for the main string (a thick piece of weed-eater nylon) and one for the plain cotton string that, like the device used by Prin, remotely controls the volume of "bridge buzz" produced. This last feature is really handy and simple to set up by placing a few eye-screws in the correct places along the body.
