Tromba Marina
Owen Morse-Brown (England)
-Materials: Body/Top: Cherry/Spruce • Bands: Ebony, holly • Soundhole: Parchment
-Length: Unlisted [possibly around 2 meters]
-Strings: 23 - 1 playing [gut], 22 sympathetic [metal]
-Other Notes: The Tromba Marina is meant to be played entirely with harmonics along the single gut string on the outside, usually with a number of resonating metal strings within the body. The instrument pictured has 22, tuned to the same note as the external string. The bridge has two feet, but one is left to vibrate freely against the spruce top. The amount of vibration can be adjusted minutely using the secondary, smaller string. The result is a very brassy sound, hence being named ‘Trumpet Marine’. Here is a picture of the maker in playing position:
