Sorry about the crude build construction. This is one of my many instrument builds. I have made and posted the instruments. Bugle, trombone, serpent, trumpet and pocket trumpet. The valves move by activation group and use the fire guns to shoot musical notes. Dont know what a flugelhorn is? The flugelhorn (/'flu?g?lh??rn/—also spelled fluegelhorn, flugel horn, or Flügelhorn—from German, wing horn, or flank horn German pronunciation: ['fly?gl?h??n]) is a brass instrument pitched in B? which resembles a trumpet, but has a wider, conical bore. The instrument known today as the flugelhorn is a descendant of the valved bugle,[1] which had been developed from a valveless hunting horn known in eighteenth-century Germany as a Flügelhorn.[2] The valved bugle provided Adolphe Sax (creator of the saxophone family) with the inspiration for his B? soprano (contralto) saxhorns, on which the modern-day flugelhorn is modeled.[2][3]
